  Select a standards document:
- Standards for Mathematical Practice[K-12]
- Make sense of problems and persevere in solving them.[K-12]
- Reason abstractly and quantitatively.[K-12]
- Operations and Algebraic Thinking[K - 5]
- Represent and solve problems involving addition and subtraction.[1 - 2]
- 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.[1]
- 2. Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.[1]
- Understand and apply properties of operations and the relationship between addition and subtraction.[1]
- 3. Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) 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.)[1]
- 4. Understand subtraction as an unknown-addend problem. For example, subtract 10 — 8 by finding the number that makes 10 when added to 8.[1]
- Add and subtract within 20.[1 - 2]
- 5. Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).[1]
- Work with addition and subtraction equations.[1]
- 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.[1]
- 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 = .[1]

  A good supplement
  By Uncle Bob on 04/15/2013 - 11:21
- A good number and variety of problems on number and picture patterns, comparisons and other forms of algebraic thinking to help supplement the problems offered in textbooks.
