### Description

Graphic workbook containing exercises on the following topics:

- Word problems requiring the use of addition and subtraction (within 20), using objects, drawings and equations

- Word problems involving addition of three whole numbers whose sum is less than or equal to 20

- Use of properties of operations as a means to solve sums and subtractions

- Understand subtraction as an unknown-addend problem.

- Count to 120. Reading and writing within the stated range, and representing a number of objects with a written numeral.

- Comparing the lengths of two objects indirectly by using a third object and ordering three objects by length.

- Distinction between defining attributes and non-defining attributes; building and drawing shapes to possess defining attributes

### Standards

to see state-specific standards (only available in the US).
Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
Apply properties of operations as strategies to add and subtract. 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.)
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.
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.
