MMR (Make Math Real)
Prologue:
As a teacher of maths Ill start by numbers, 15 years ago I was a student in faculty
of education in Ain Shams University, and since that time, Im searching for a method to
make maths real especially in my primary school. But for the good luck when I was in a
mission in Scotland 2004, I found a maths teacher called Richard Dunne. This old man
had the same problem and we made some workshops to find a method that Making
Maths Make Sense and at last was the great idea to use something looks like the first
man used to count calculus but must be familiar to our pupils so what about the soft
drink CUPS? Yes thats great, so my method is to use the CUPS. And because doing
something is the best way to learn it, we will act Mathematics operations using these
cups.
INTRODUCTION:
To make math real is the aim of this project by acting math concepts and
operations or by translate each math word into an action, so we have to usematerials that help our pupils to act math and make it real. The pupils will act math
in front of the class using concrete materials then using cards or what so called
pictorial materials, and at last using symbolic materials.
Ill concentrate on the big ideas of math which taught in primary schools as a
beginning.
The Big Ideas of Math1) Addition2) Subtraction
3) Multiplication4) Division5) Equals
Make Math Real (MMR) materials are designed to ensure that mathematics can
be taught so that it actually makes sense for all pupils. Teaching mathematics inan accurate way will ensure improve skill. It does require some study on yourpart but this work will be fully satisfied. The return is not only in the confidenceand ability of pupils; it is also in your recovering the complete enjoyment ofteaching.
Make Math Real (MMR)does not introduce new content (it is not newMath). Nor does it require expensive equipment. Its great value is in the fact thatit is based strictly on a powerful theory of instruction. The theory of instructionis widely applicable and similar materials have been designed for other schoolsubjects. In particular, it recognizes, develops and applies the difference betweenscientific conceptsand everyday concepts.

MMR (Make Math Real)
In MMRThe plastic ( or paper) cups provide an educational object, this beingsomething that is used on purpose and only for the purpose of teachingbecause its use best represents the nature of what we want pupils to do. It isnot intended to be interesting. It does not offer any variety. You will see that
it is something for pupils to think with; not to think about. When pupils havedifficulty in recalling something they can return to objects that are veryfamiliar to them.
In MMRif you look at the first five Big Ideas + = below, you will seethat they are introduced in relation to two tables at the front of the class: theResources Table or Math Box (to the left) and the Math Table (to the right).Cups on the Resources Table or in Math Box (to the left) are moved to theMath Table (to the right).
Note that the Resources Table and the Math Table are themselves educational
objects.

MMR (Make Math Real)
In MMR the language is very important.
Note in particular that looking at, say, 3 + 2 5, when the teacher says Readwhat it says, pupils respond with Three add two equals five. But when theteacher says Read what it means the pupils say Three cups add two cupsequals five cups.
In MMRwe need to be clear about the helper Units(CUPS).Look at reading what it means for each of these:3 + 2 5 Three cups add two cups equals five cups3 2 1 Three cups take away two cups equals one cup3 4 12 Three cups times four equals twelve cups6 2 3 Six cups divided by two cups equals three
This is because the educational object of cups is used to provide the highlyabstract equation 3 + 2 5 with a unit. But the unit is entirely imaginary;it is artificial; it is there because it enables learners to make sense of
something (3 + 2 5) that is otherwise so abstract it virtually defeatsunderstanding. The cups, introduced for educational reasons into numericalequations, are to be thought of as the Helper unit.
Let me return to the Big Ideas. Look first at the basic 3 + 2 5. In establishingfor educational reasons that we think of cups, the figures (3, 2 and 5) are
thought of, by the teacher, as nouns. But the + and the , being instructionsrequiring an action, are to be thought of as imperative verbs. And, of course,each of is an imperative verb. Therefore, 3 + 2 = 5 is thoughtof as:Noun imperativeverb noun imperative verb noun3 + 2 = 5
With this recognition in your mind, and the consequent ability to representsymbolism to learners in an active and visual way, you are well on the way to
successful teaching. Notice also that simply writing, say, on the board willdrive all your pupils to raise their hands in the general direction of theResources Table (math box). The symbol, and each of the symbols, has ameaning and some speech (eg Get ready to get some more) that can be
enacted in the absence of any surrounding numbers. In MMR the symbol does not require a context! It is therefore open to general use. It can be aseasily used with large numbers, fractions, decimals, negative numbers andalgebraic symbols as it can with small numbers. And that is the unique power

MMR (Make Math Real)
of MMR. It teaches pure math to learners. It reverses the trend of trying toteach math always from a context. It is difficult to find any justification for
teaching math in context
The pattern of the appearance of the Helper Units for and in the last two,
is very different from + and
in the first two. That is why MMR refuses thepressure to teach multiplication as repeated addition. It is educationallyunsound because it entices learners to misunderstand the meaning of
multiplication. It is no good asserting to me that multiplication is repeatedaddition. Of course it is. But that is not the point. What I am talking about
here is how to design instructional methods that make math clear to pupils.What justification can there ever be for continuing with an approach that isdesigned to confuse?Multiplication must be in introduced separate from any mention of addition. Itis a Big Idea in its own right. Later, pupils will identify that repeated additiongives the same result as a multiplication: but that will be part of an on purpose
planned chance for symbolic reasoning. This act of reasoning (this act ofdiscovery; this act of creativity) can only take place if multiplication hasbeen introduced in its pure form. Equally, it is counter-productive tointroduce division as repeated subtraction because it is confusing for young
pupils and does not lend itself later to using factors. It is the logic of teachingdivision like (e.g. 3 = 6) and (7x 7 = x) that illustrates themethodology that pervades MMR. The Big Ideas + - x = are, remember, BigIdeas in their own right.

MMR (Make Math Real)
Teaching the four operationsThe four operations ( +, - ,, ) are central concepts in teaching math. Theyare best taught in a way that applies unchanged to small numbers, large
numbers, vulgar fractions, decimal fractions, negative numbers, algebra andmuch else.
This avoids the multitude of rules generally taught in math In MMR, + - and = are given much more significance than is generally given. They are thefirst five Big Ideas designed to ensure rigorous math is accessible by all pupils.The manner in which they are taught is crucial to all subsequent learning.There is an essential feature that must be in the teachers mind in using theMMR Scripts to teach the first five Big Ideas. Each of the symbols + - = isto be thought of as an imperative verb; it is an instruction; it can be enacted
without reference to the symbol (usually a number) that follows it. When wesee 3 + 2 we do notsay3 [pause] add 2but 3 [pause] add [pause] 2.Each symbol is treated separately. It is for that reason the script below insiststhat + means get ready to get some more.You can see that 3 + 2 = 5, and all similar expressions, have the form:Noun; imperative verb; noun; imperative verb; noun. They have this formbecause cups are used as a proxy for the indeterminate object 3. The cupsenable you to think about the math.
This importantnoun; imperative verb; noun; imperative verb; noun form isuniversal. It is achieved by ensuring that novices without exceptionlearn that + means Get ready to get some more - means Get ready to take some away means Do the same thing lots of times means Look at it and wonder about = means Lookat the Math Table and count It is absolutely vital that each operation is thought of as an imperative verbprovoking a specific action without reference to the noun that follows. Inessence 3 + 2 = is thought of as what you start with; the type of job; the size
of the job; look at the math table; . This practiced set of actions ensures that
young learners inspect each symbol carefully (rather than assume any twonumbers on the page are inviting addition) and that this enables olderlearners to deal logically (rather than impulsively) with negative numbers,algebraic symbols etc.

the figure 32 + 1 = 3The numbers and signs have been written one by one (so that each is acted bythe helper) to build up the expression 2 + 1 = 3Learners need to understand expressions like 2 + 1 = 3 as a series ofinstructions that can be interpreted as physical actions and eventuallyvisualise as images of those physical actions.Detailed Notes1) The script above is illustrative. In fact, it is important to use longerexamples right from the start ( e.g. 3 + 1 + 2 + 2 = 8) so that pupils get usedto reading the symbols and responding to them (rather than assume thatthere will always be just two numbers before the arrival of the equals sign).
2) When 3 + 1 + 2 + 2 = 8 (for instance) has been acted, pupils need to betaught to respond to Read what it says by saying Three add one add two addtwo equals eightand to Read what it means by saying Three cups add onecup add two cups add two cups equals eight cups.

3) When the teacher writes 3 + 1 + 2 + 2 = 8 (this is called a Math Story)pupils must be taught to act the Real Story (i.e. to act it with the cups). So
they must respond to:I will write the Math Story. You act the Real Story.
4) When the teacher acts the Real Story (i.e. acts it with the cups) pupilsmust be taught to write 3 + 1 + 2 + 2 = 8 (this is called a Math Story).Detailed attention must be given to ensuring they form their numbers andsymbols correctly. So they must respond toI will act the Real Story.

attention must be given to ensuring they form their numbers and symbolscorrectly. It is extremely important for pupils be made to see that having got
as far as 3 they know by looking at the writing that the next thing theteacher will do is already known. The teacher will pick up three cups
because it says so! Itis the three cups that I loved. You know that. It says so.What you do not know is how many times I will walk. Do not write. Wait! Nowyou can see I have finished walking you can see how many times I walked.Four! So write it. So they must respond to: I will write the Math Story.You act the Real Story.5) The whole point of 3) and 4) above is to create an instinctive relationshipbetween the Math Story and the Real Story. but they must be taughtcarefully to interpret the symbols.6) After practice with examples containing only a times and an equals sign,move to longer examples that use plus and minus signs as well.
7) Of course, pupils do not always respond only to the symbols written one byone. I general, they see something like 3 4 = and put three cups on the MathTable and then, knowing there is a multiplication sign, move immediately
from the Math Table to the Resources Table to do the same thing. At this stage,they are not pausing at the Neutral position after putting the first three cupson the Math Table. It is this non-pausing that distinguishes multiplicationfrom addition and, pedagogically, we want novices to make that distinction.8) MMMS makes the distinction absolutely deliberately. Do not mentionanything aboutmultiplication being repeated addition. It is not! Look for
instance at7 2 3 = 1 to appreciate the meticulous rigour ofMMMS. We putseven cups on the Math Table; get ready to take away; move to the ResourcesTable with two cups; then do the same thing (i.e. move to the Math Table withtwo cups) lots of times. This is certainly not repeated addition.Practise with examples like these:3 4 = 12 2 5 = 10 1 5 = 5 0 4 = 02 4 + 1 3 = 11 2 4 - 1 3 = 5 5 + 2 3 = 11 7 2 3 = 1Do not use any rules. Teach the immutable logic of the (symbolic) language.
For instance, in 7 2 3 = 1 I start by putting seven cups on the math table; Iget ready to take away. I then walk to the Resources Table with 2 cups. It isthat (walking to the math table with two cups) that I loved. So I do it threetimes altogether. That is why the correct answer (the only correct answer) isone cup. When dealing with expressions like 2 4 + 1 3 = 11 ensure it isunderstood as: Put two cups on the table. Do the same thing lots of times.Walk to the math table four times altogether. Get ready to get some more. One.

Preparation for teaching DivisionBefore showing the actions for division you need to establish the importantidea of
Same Value; Different Appearance by using a version of this script:
Is this the same as this ?
Yes it is (because there is still six cups). No it is not (because these are on thetable and these are piled up). So the answer is: yes it is; no it is not; yes it is;
no it is not; yes it is; no itis not; yes it is; no it is not.The answer that mathematicians give is Same Value: Different Appearance.This is, of course, an important aspect of equality (i.e. the equals sign).Although it is true that 3 = 3 it is boring (same value; same appearance). On
the other hand 2 + 1 = 3 is interesting (Same Value: Different Appearance)The phrase and the idea ofSame Value: Different Appearance is in fact usedmuch earlier than this (in Reception) but it needs specific attention inrelation to division
