Dino Soar | Decomposing Teen Numbers Game

Dino Soar - An adventurous game designed to help children understand the concept of decomposing teen numbers while having a blast. As your dinosaur character races through the prehistoric skies, they will find teen numbers broken down into tens and one on dino eggs. Each correct answer helps your dinosaur to soar higher and faster. The game encourages children to break down teen numbers into tens and ones, understanding the role of each in the number's composition. This fundamental skill in mathematics provides a stepping stone to more complex number operations. Help your dinosaur win the race and master decomposing teen numbers with Dino Soar!

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).
