# Kitty Princess Rainbow Maker | Decomposing Teen Numbers Game

Rainbow Maker - You're in charge of creating dazzling rainbows! Your buddies, Pretty Kitty Princess and Sassycorn need your help. They've got a big pot, and they need to make a rainbow mix. But here's the twist – you need to decompose teen numbers correctly to create the perfect mix. Decomposing numbers means you're breaking them down into smaller parts. For the teen numbers, you're breaking them down into tens and ones. It's a fun way to understand the numbers we see and use every day. For each correct answer, a beautiful rainbow shoots up and travels down the conveyer belt ready for delivery. Ready to help Pretty Kitty Princess and Sassycorn make the most vibrant rainbow mix? Let's decompose some numbers and get this rainbow party started!

## 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).
