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
