Looking for a fun way to practice composing and decomposing numbers with your kinders or first graders? This printable book is designed to help students master the concept of tens and ones through the use of ten frames and drawings. Students can complete this book during whole class instruction, small guided math groups, or independently depending on students' skill levels.
There are two differentiated books. One consists of composing and decomposing numbers 11-20 and the other allows students to compose and decompose ten different two digit numbers.
This activity book addresses the following Math Common Core State Standards:
K.NBT.1.c. Record the composition of numbers 11-19 through drawings of a group of ten ones and additional ones.
K.NBT.1.d. Record the decomposition of numbers 11-19 through a drawing of a group of ten ones and additional ones.
