Choose the missing number to load the waiting train. Notice the relationship between the engine's number and the product on its carriage, rather than guessing at the biggest option.
How to play
- Read the engine and carriage together.
- Choose the number that completes the fact.
- Say the completed fact aloud before the next carriage.
Make one useful connection
After a turn, ask “How did you work that out?” Try an array, a known fact or real objects if an answer is uncertain. Moving, holding and remembering are extra skills; choose another interaction if those get in the way of the numbers.
