Substitution

Thank you for sharing this. I used it with a class during an informal observation and the observer joined in and thoroughly enjoyed it so did the class.

Looks good thank you.

Looks great & saved me some time... thanks... - one mistake though. Either change question 8 to: a - 8 = ? or change -4 in the grid to -2 :-)

Great bingo resource that can be easily altered to differentiate for your own group

A great resource thanks!

Thank you. This is a great resource.
