# Math: Introducing Addition and Equality within 10

### Suggested Time Frame: 20 Instructional Days

##### Focus TEKS

Composing and Decomposing within 10

• K.2I compose and decompose numbers up to 10 with objects and pictures

Developing the Concepts of Addition and Equality

• K.3B solve word problems using objects and drawings to find sums up to 10 and differences within 10
• K.3A model the action of joining to represent addition and the action of separating to represent subtraction
• K.3C explain the strategies used to solve problems involving adding and subtracting within 10 using spoken words, concrete and pictorial models, and number sentences
##### Computational Fluency TEKS

Number Sense

• K.2D recognize instantly the quantity of a small group of objects [up to 10] in organized and random arrangements

Counting Patterns

• K.5 The student is expected to recite numbers up to at least 100 [50 in this unit] by ones and tens beginning with any given number
##### Spiral Review TEKS

Counting Collections

• K.5 The student is expected to recite numbers up to at least 100 [50 in this unit] by ones and tens beginning with any given number [beginning with 1 in this unit]

Sorting and Displaying Data

• K.8B use data to create real-object and picture graphs
• K.8A collect, sort, and organize data into two or three categories
• K.8C draw conclusions from real-object and picture graphs

Sorting and Classifying 3-D Figures

• K.6E classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size
• K.6B identify three-dimensional solids, including cylinders, cones, spheres, and cubes, in the real world
• K.6C  identify two-dimensional components of three-dimensional objects

Sorting and Classifying 2-D Figures

• K.6E classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size
• K.6A identify two-dimensional shapes, including circles, triangles, rectangles, and squares as special rectangles
• K.6D identify attributes of two-dimensional shapes using informal and formal geometric language interchangeably
• K.6F create two-dimensional shapes using a variety of materials and drawings
