**Activities and Lessons by Strand**

(activities listed are from: Illustrative Mathematics, Inside Mathematics, LearnZillion, Howard County Common Core Assessments)

*Domain: Operations and Algebraic Thinking 1.OA*

**Standard A (Represent and solve problems involving addition and subtraction): **

**A1 (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):**

Hopping Along the Number Line (go to page 51 of the PDF, other activities, too!)

May/June Calendar Markers (go to page 133 of the PDF)

**Standard B (Understand and apply properties of operations and the relationship between addition and subtraction):**

To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12--Associative property of addition):**
