Common Core - Numbers & Operations - Compose and Decompose - Puzzles (Stringing Facts Puzzles). These fun, self-checking puzzles allow students to:
* decompose numbers less than or equal to 10 into pairs
* find the number that makes 10 when added to the given number
* compose and decompose numbers from 11-19 into tens and ones
* solve problems in centers and self-check their work
* play games of speed with addition facts
The puzzles consist of practice problems that the students solve and then match their answer with a piece of string that will wrap from the problem to the answer on the front. Detailed instructions for how to put together the puzzles are includes.
These puzzles cover the following Common Core Objectives for Kindergarten but can also be used for struggling learners in 1st grade or learning who are excelling in Pre-K.
CCSS.Math.Content.K.OA.A.3 Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
CCSS.Math.Content.K.OA.A.4 For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
CCSS.Math.Content.K.NBT.A.1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
