﻿This unit of math study is designed specifically for first graders but can be tailored to meet the unique needs and learning styles for students in other grades. This unit focuses onvisual patterns, number patterns and counting. Strategies for differentiated instruction are offered for each lesson.

**(+)** refers to students on or above grade level **(+/-)** refers to students approaching grade level **(-)** refers to students below grade level *Teacher should introduce activity and then return periodically to help as facilitator
 * Key for Differentiated Practice **

The lessons apply to the following Common Core State Standards:

Represent and solve problems involving addition and subtraction.
 * Operations and Algebraic Thinking 1.OA **

1. Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

Add and subtract within 20.

5. Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).

Work with addition and subtraction equations.

7. Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.

8. Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 +? = 11, 5 = 􀃍 – 3, 6 + 6 = 􀃍.
