Students will quietly walk around the classroom to find the person with the matching paper. Let’s throw math around!
This is a College- and Career-Ready Standards showcase lesson plan.
**Standard(s): **

[MA2015] (1) 12: Add within 100, including adding a two-digit number and a one-digit number and adding a two-digit number and a multiple of 10, 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, and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten. [1-NBT4]
