The big idea of this lesson is the understanding that addition can be represented as parts of a whole and that we can use addition sentences to represent those parts.

Write addition number sentences using the commutative property.

Use your problem solving skills and move the dominoes around on the square so that each side has only eight dots. When you are finished you can check your answer against theirs right at this one page NRich website.

On this one page website move the domino pieces around until you satisfy the rules for this challenge. This will require you to use your problem solving skills.

This page offers a variety of math center ideas for general math and geometry. Instructions on setting up the center are not provided for most ideas, however, those lacking instructions are pretty self-evident.

Fantastic for improving your mental maths. Similar to dominoes, complete the loop against the clock while practicing addition, subtraction, multiplication, and division.
