# Double Facts within 10

Having learned to add numbers within 10, first graders can build on their understanding of addition with this doubles facts game. Internalizing these facts helps children build fluency in single-digit addition. Pictures, drag and drop features, addition sentences - all of these make your child’s experience much more entertaining and comprehensive than a regular worksheet can provide.

What’s inside?

- Double numbers using pictures.

- Understand addition sentences and double numbers without pictures.

Real-World Application

Fluently doubling numbers helps us process simple addition problems easily. For example, when children realise that 5 + 7 is also 5 + 5 + 2, the addition becomes way simpler. The ability to form such mental models enables children perform basic math mentally.

What’s next?

Now that children can double numbers under 10 fluently, they can strengthen this understanding by working on part-part-whole models, visualizing a sum (whole) being made up of small parts.

### Common Core Alignment

1.OA.6Add 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).
