Equality

We have been looking closely at the equal sign in our math number sentences this week and have been focusing on what this means.  Equality is a big component of first grade math and we will be working on it throughout the year.  This week, students are looking at different "expressions" that are equal and not equal to each other. For example, students are seeing that 5+5=2+8 but 5+5 is not equal to 3+8.  We are working on making these false number sentences (5+5=3+8) turn into true number sentences.  As we continue understanding this concept, students have spent more time on the commutative property (changing the order of the numbers involved without changing the result) and seeing how this does not effect the sentence.  Have your child try a few out at home - can they tell you if these number sentences are true or false? If false, have them figure out a way to make it true! 
(examples 2+3=1+4, 4+2=3+3, 7+1=4+4, 5+4=1+8)
