What addition and subtraction do children learn in 1st grade?

In 1st grade (ages 6–7), children add and subtract within 20 using strategies such as counting on, making ten and doubles. They learn fact families, see how addition and subtraction relate, and work toward knowing facts within 10 from memory. Grade levels vary by country and school.

How does RepeatWatch help with math facts?

Put a doubles or make 10 song on Repeat one while your child practises facts on paper. Drag an A–B loop around one worked example, such as making ten to solve 8 + 5, drop to 0.75× for a tricky step, and save lesson parts to keys 1–9.
