Daily 5 Math Practice: 24 Oct Worked Solutions

A first attempt that goes wrong is not wasted effort. When a child tries a question, gets stuck and only then looks at the working, the step they missed tends to stay with them far longer than a method they simply watched. That is why we lay these posts out the way we do: the five questions from each grade's video, with every hint and step tucked away until your child has had a real go. Trying first and checking second is a small habit, but it builds the kind of confidence that comes from finding a gap on your own rather than being shown it.

Start with the video for your child's grade, then put it away and have your child attempt the five questions on paper. To check a question, open its worked solution and stop after the first hint; often that is enough for another try. The working shown matches the video step for step.

Primary 1 (P1) Math: Whole Numbers, Money, Statistics

This P1 set moves between sharing equally, counting a mix of coins, adding two scores, finding a missing part with number bonds, and comparing two rows of a picture graph. Several questions come with a bar model or a picture, so give your child time to look at it before counting. In the coin question, ask them to say what each coin is worth before they start.
