Roll and Go

We are busy reviewing our different concepts from Chapter 2 - Estimation and Number Theory.  Some of the concepts we're working on are front-end estimation, rounding, factoring, finding GCF, multiples and finding LCM.

Today during teacher led pod in math students did an activity called "Roll and Go".  First they rolled two different coloured dice.  Then they made a 2 digit number with the two digits from their dice (ie. if they rolled a 4 and a 5 they could make 45 or 54).  They did this twice to make 2 different two-digit numbers.  Next they found the factors for each and then listed all the common factors.  Finally, they looked at the common factors and noted the GCF (greatest common factor).

Yet another way we can review concepts while having fun, mixing up our methods and using our critical and creative thinking skills.  As well it allowed us to give our metacognition some work as we could evaluate: a) which number created would be easier for us to find factors for, and b) using a t-chart or line to list factors depending on how our mind works.'
