Breaking Apart Numbers: Practice Sheets May 27, 2014

Screen shot 2014-05-27 at 10.57.33 AMI have mentioned before about the importance of breaking numbers apart, of having students understand that every number can be broken into smaller numbers. I have included this practice on all of the Number of the Day sheets (level l, level ll, level lll) that I have posted, but it warrants adding these other sheets that focus on this Whole-Part-Part number relationship.

Regularly practicing this skill can change students’ thinking. They will be much more likely, in any given situation involving numbers, to look for alternative ways of thinking if they have spent time pulling numbers apart in many ways.

Remember, the students are not starting with a new number in every circle. Rather they are using one particular number for a line or for the whole page! In different situations it may be more beneficial to break a number apart in one way than it is in another way.

Mathematically yours,
