This comprehensive presentation has been created to guide students through strategies to solve their multiplication facts for the threes. These strategies include- repeated addition, skip counting and the use of arrays. The presentation also explores the related division facts for the threes. It goes through how fact families and the use of arrays can help with the recall of the threes facts. This presentation is part of the Year 3 Unit of Work- Terrific Threes.
