## Weekly Overview

Weekly Topics

The focus of this week’s instruction is to deepen students’ understanding of:

• Represent pictorial decomposition and composition addition stories to 10 with 5-group drawings and equations with no unknown.
• Solve add to with total unknown and put together with total unknown problems with totals of 9 and 10.
• Represent subtraction story problems by breaking off, crossing out, and hiding a part.
• Add 1 to numbers 1–9 to see the pattern of the next number using 5-group drawings and equations.
• Find the number that makes 10 for numbers 1–9, and record each with an addition equation.

Materials Needed

• Student Print Packets for each day
• Kindergarten Templates
• End of Week Assessment
• Dry Erase Markers
• Sheet Protectors
• Teacher Rekenrek
• Beans, bears, counters
• Linking cubes (2 different colors)
• Pattern blocks

Standards Covered

K.OA.A.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.

K.OA.A.2 Add and subtract within 10 to solve contextual problems using objects or drawings to represent the problem.

K.OA.A.3 Decompose numbers less than or equal to 10 into addend pairs in more than one way (e.g., 5 = 2 + 3 and 5 = 4 + 1) by using objects or drawings. Record each decomposition using a drawing or writing an equation.

K.OA.A.4 Find the number that makes 10, when added to any given number, from 1 to 9 using objects or drawings. Record the answer using a drawing or writing an equation.
