FOURTH:Now that we know how to identify addition problems we need a plan on how to solve them! Pull out your counting hands sheet!

Fingers can be a great way to help with addition!Let’s find out how!

click on the magnifying glass

Who knew you could use your

fingers for addition?

You all are so smart!

FIFTH:Now that we can count with our hands let’s learn a new way! Pull out your number line sheet!

When using a number line you set the frog on the first number. Then the frog jumps the second number. What he lands on is the answer!

2 + = 3 5

Click on the spider for more practice with number lines!

Finally, an addition tool I can really jump into!
