Core Skills Analysis
Mathematics
- Tyler practised ordering positive and negative whole numbers by counting forward and backward along the number sequence.
- He developed an understanding that moving forward increases a number, while moving backward decreases it, including when counting across zero.
- The activity supported Tyler’s use of number order and the number line as a model for positive and negative integers.
- Repeated counting helped Tyler build fluency with integer sequences and recognise how numbers relate to one another.
Tips
Tips Build on Tyler’s integer fluency with a life-size number line on the floor: call out a starting number and have him step forward or backward to reach a target. Next, use a thermometer or imaginary lift journey to connect negative numbers to familiar contexts. Invite him to invent and explain a counting sequence that crosses zero, then compare different routes to the same answer. Finish with a short partner game in which one person gives the starting number and direction and the other predicts the destination.
