math strategies (envision math users)
07082017, 05:04 AM


I teach first grade in a private schools. Many of the schools around us are now using envision math, not us, and I want my students to be prepared or at least familiar with the addition/subtraction strategies that are being taught at other schools that use envision math because our math program is not nearly as complex. So far, I get the making 10 strategy when adding numbers that equal more than 10 or subtracting numbers higher than 10 but i have 2 questions:
1. Are there certain addition or subtraction strategies that are being taught differently now? How would you teach your first graders to solve 9  6? It seems like students are expected to somehow memorize all addition partners for each # thru 10, HOW do they do that in such a short period of time? Should I no longer be teaching the counting up strategy to solve 5 + 4 and only be teaching them to know right away that 5 and 4 make 9?
2. In order for first graders to really be able to use the making 10 strategy to add they need to be very fluent with addition facts thru 10. For many first graders that takes a very long time so my question is, approximately when in the school year do you start teaching the make 10 to add strategy?
3. Lastly, is the breaking apart 10 strategy just another way to teach regrouping?
thank you
