I’m working with Year 5 at the moment, thinking about how to get Scratch to do maths. The progression has been something like this…
1) Get sprite to say the answer to 3*2 etc
2) Get sprite to ask for something to multiply by 2. Eg ‘say *2′
3) Set first answer to a variable called ‘firstnumber’ and second answer to variable called ‘secondnumber’ then get the sprite to ‘say firstnumber*secondnumber’
4 Use a ‘join’ to make the sprite to say ‘The answer to [firstnumber] x [secondnumber] is [firstnumber*secondnumber]’
