Doubling and Halving Riddles

Not only is this great for introducing solving equations in pre-algebra, as well as a basic algebra review, your activity gave me an idea for developing a similar activity using exponents for my Algebra 2 students! Hopefully, I will get it done and posted before the end of the summer! This interactive activity could easily be converted to an "I have . . . / Who has . . . ?" format as well as a "BINGO" or "Tic Tack Toe" game! :) Thanks for reminding us to keep math practice fun - students don't mind doing repeated practice when it's in a game or team competition format!

I can see using this with middle school students learning to write algebraic equations and solve them. Very nice - thank you!

Wow very inspirational for me the pupils will enjoy this activity thanks
