Over the past few years there has been an abundance of research supporting the idea that standing while learning may help us take in, process, and retain information, particularly when it comes to math. In grade 7 we've embraced this idea and try to give the students ample opportunities for collaborative vertical learning on non-permanent surfaces.
This week we asked the 7s to experiment with one of my favourite math prompts: choose 4 numbers between 2 and 6 and use them, together with any of the operations (+ , - , x , /) to create expressions equalling the numbers 1-30. Sounds simple, doesn't it? It's actually not as easy as it seems.
Working together, students test their computational fluency skills and access their knowledge of order of operations to create the 30 expressions.
Once completed, I challenged the students to revisit their expressions and rewrite any in which they used the same number more than once. Ex: 4x2+5-2=11...could they create an expression for 11 that doesn't need two 2s?
Feel free to try this one at home! Choose any 4 single digit numbers and any range of answers and ask your child to create the corresponding expressions. A fantastic way to practice math facts and review order of operations!
