“ …describe ways in which developing student practitioners of the discipline of mathematics increasingly ought to engage with the subject matter as they grow in mathematical maturity and expertise throughout the elementary, middle and high schools years.”
11© 2011 California County Superintendents Educational Services Association • Mathematics Teacher Overview
1. Make sense of problems and persevere in solving them…start by explaining to themselves the meaning of a problem and looking for entry points to its solution
2. Reason abstractly and quantitatively…make sense of quantities and their relationships to problem situations
3. Construct viable arguments and critique the reasoning of others…understand and use stated assumptions, definitions, and previously established results in constructing arguments
4. Model with mathematics…can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace
12© 2011 California County Superintendents Educational Services Association • Mathematics Teacher Overview
5. Use appropriate tools strategically…consider the available tools when solving a mathematical problem
6. Attend to precision…calculate accurately and efficiently
7. Look for and make use of structure…look closely to discern a pattern or structure
8. Look for and express regularity in repeated reasoning…notice if calculations are repeated, and look for both general methods and for shortcuts

Develop Conceptual Develop Conceptual UnderstandingsUnderstandings
Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem. (K.OA.2)
Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds. (2NBT.7)
26© 2011 California County Superintendents Educational Services Association • Mathematics Teacher Overview
Emphasis on FluencyEmphasis on Fluency
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g. knowing that 8 x 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of grade 3, know from memory all products of two one-digit numbers. (3.OA.7)
Fluently multiply multi-digit whole numbers using the standard algorithm. (5.NBT.5)

A Strong Focus on FractionsA Strong Focus on Fractions
Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line. (3.NF.2.a)
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g. by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5+ 1/2 = 3/7, by observing that 3/7 < 1/2. (5.NF.2)
28© 2011 California County Superintendents Educational Services Association • Mathematics Teacher Overview
Fraction ConceptsFraction Concepts Compare two fractions with the same
numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model. ( 3.NF.3d)
Discuss how you might compare pairs of fractions using a visual fraction model. For discussion purposes, use the following two fraction pairs:
7/9 and 4/9 (same denominator)4/9 and 4/7 (same numerator)

Goal for 8th grade students is Algebra 1
Not all students have the necessary prerequisite skills for Algebra 1
Two sets of standards for grade 8
◦ Each set will prepare students for college and career
◦ Standards for Algebra 1
Taken from 8th grade Common Core, high school Algebra content cluster and CA Algebra standards
◦ 8th grade Common Core
Goal of grade 8 Common Core is to finalize preparation for students in high school

Fifth Understand the concept of multiplication and division of fractions.
Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions. (A unit fraction is one with a numerator of 1 and the denominator is a positive integer)
Sixth Interpret and use ratios in different contexts (e.g., batting averages, miles per hour) to show the relative sizes of two quantities, using appropriate notations ( a/b, a to b, a:b ).
Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
Seventh Use variables and appropriate operations to write an expression, an equation, an inequality, or a system of equations or inequalities that represents a verbal description (e.g., three is less than a number, half as large as area A).
Use variables to represent quantities in real-world and mathematical problems and construct simple equations and inequalities to solve problems about the quantities.
