# Taterz Quiz-O-Rama | Decomposing Teen Numbers Game

Taterz Quiz-O-Rama - Step into Taterz's classroom and lend her a hand as she studies for her quiz on decomposing teen numbers. In this game, Taterz is counting on you to help her understand how to break down teen numbers into tens and ones. Decomposing numbers might sound like a big task, but it's actually a fun way to understand numbers better. Plus, for every correct answer you choose, Taterz trades eggs. The more eggs you collect, the better! Are you ready to help Taterz break down teen numbers and collect all the eggs? Let's hop into the classroom and start solving!

## 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).
