Puzzles and Riddles
Learning Goals:
- Multiply and divide whole numbers using a variety of tools and strategies
- Determine the missing numbers in equations
- Develop and apply reasoning skills to make and test math predictions
The Challenge:
The goal of these Kakooma puzzles is to find which number in each section is a product of two other numbers found there (which number can be an answer by multiplying two others?) Once you have found the product in each section, use all 4 products to create 1 final addition puzzle and solve to get your final answer (which of the special numbers from each section is the sum of two of the others?) Here is a solved example:

Questions and Prompts to Support your Child:
- What have you tried so far? What could we try together?
- If you feel stuck, try eliminating numbers that couldn’t be the product of any of the others first. It might help you see things differently!
Extensions & Adaptations:
- If calculations are feeling too tricky, grab a calculator!
- Try creating your own kakooma puzzles by starting each section with three numbers that complete a multiplication sentence, then adding in some extra numbers that don’t. Make sure to still include numbers that are close, to keep your puzzles challenging.
