Number partners

A huge part of mathematical understanding is rooted in the vocabulary in math.  Each day students practice using the vocabulary accurately to explain their thinking. As their mathematical thinking and understanding develop, their vocabulary and explanation of their thinking does as well.

Currently, we are working on finding number partners to numbers 2-10.  Number partners are pairs of numbers that can be added together to create the total.  

Example:

Total: 5

Possible number partners: 0+5=5, 5+0=5, 1+4=5, 4+1=5, 2+3=5, 3+2=5

Questions you can ask to extend their learning:

What are number partners?
What are switch partners?
Can a number sentence start with a total (5=0+5)?
