Today we were working through the factors and multiples information page and I noticed one thing that I wanted to ask about.
I really appreciated the clarity of the organization and the way the images of the arrays was incorporated into the lesson. I also like the number of practice / check problems to help my student know if he was on the right track.
But I was quite bothered by the wording in this section,
Finding factors without pictures
The next line states, "We can find the factors for 16 without drawing dots by thinking about numbers that will divide into 16 evenly."
When it says divide into 16 evenly, it sounds to me like the factor is being divided.
Another example is here, "2 is a factor of 16 because 2 can be divided into 16 with no remainder."
2 doesn't get divided to fit into 16. Instead 16 is being divided into groups of 2 OR 16 is getting divided into 2 groups. Would it be better to say, 2 is a factor of 16 because 16 can be divided into equal groups of 2 or it can be divided into 2 equal groups?
I don't know if you've tried different versions and found this to be the most clear, but it definitely seemed to be unclear to me, and seemed unclear to my student.
