Teaching tips & learning objectives

Learning objectives

  • Add three single-digit numbers

  • Match an addition equation to its sum

Teaching tips

  • Students can check their own sums by the card match, which leaves the worksheet as an independent check of the same skill.

  • One answer card needs correcting before use: 3 + 2 + 0 makes 5, but the answer set has two cards reading 15 and only one reading 5.

Skills covered

  • Adding three numbers — solving each equation card before searching for its answer card

  • Column addition — adding three stacked addends on the worksheet
