# Space Race | Decomposing Teen Numbers Game

Space Race - A cosmic journey designed to help your child master the art of decomposing teen numbers. The idea of decomposing numbers might seem complex, but it's essentially breaking down numbers into smaller parts. Teen numbers, for instance, can be split into tens and ones. As your child navigates through space in this game, they will encounter various teen numbers on asteroids. Their mission? To break the number down into its tens and ones. This game helps reinforce their understanding of place value, a fundamental skill for more complex arithmetic. Help your character win the race through space while gaining confidence in decomposing teen numbers!

## Common Core Standards

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 (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.

CCSS.MATH.CONTENT.1.OA.C.6

Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
