**Title:** Let's Throw Paper!! Addition Game

**Description:**
Students will throw addition problems or answers (on paper) across the classroom and find the matching problem or answer! Students will use mental math to compute the matching answer. 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]

**Title:** Fact Families

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students use books and connecting cubes to explore the relationship of addition to subtraction. Students search for related addition and subtraction facts for a given number using a virtual or actual calculator to find differences. They also investigate fact families when one addend is 0 as well as when the addends are the same. Several pieces of literature appropriate for use with this lesson are suggested.
