Understanding divisibility makes prime factorization and working with fractions easier. It speeds up the processes in fractions allowing one to being more efficient. In partner groupings, students were given sets of tested examples showing when divisibility of a given number occurred and when it did not. From those examples, partners needed to devise their own condition or rule. Then they decided on two examples in order to apply their rule.
Below is a photo copy of the charts in students' MTN's and the first two items that were completed in class together. The remaining were worked on in partner groups and will be completed in class tomorrow. A divisibility worksheet was given; due in class on Thursday, 2/12.
