Add & Take Away

Join and take away

What your child practises

Small story problems where some join or some leave (totals to 10), plus finding one more and one less.

Alberta Curriculum learning outcome: KN2.1 · adding and taking away within 10 with objects

How we explain it

Children can open this short lesson before they practise.

  1. Adding puts groups together.
  2. Taking away means some go away.
  3. Count what is left or what you have in all.

Example: 3 birds sit on a branch. 2 more fly in. How many now? Start with 3. Count on 2 more: 4, 5. Answer: 5 birds
