Addition and Subtraction

Last week and this week we are focusing on addition and subtraction. Due to student levels being greatly different, you will see several different levels of work. Some students focused on adding just to 10, while other students were able to add double digit numbers with regrouping. 

To teach this skill, I use a differentiated instruction model from How to Differentiate Instruction in Mixed-Ability Classrooms by Carol Ann Tomlinson. It's a wonderful resource for teachers and I highly recommend all teachers to read. It's a quick read that I finished during my lunch breaks. 

This model uses a blend of whole-class, group and individual instruction. I begin by teaching a lesson to the whole group. Then I have students work individually, with partners or in a small group with me to pursue learning. After 10-15 minutes of studying, I have students come back together to share what they had learned as well as teach another lesson. We repeat this two to three times depending on our schedule for that day. 

--Addition--
For students who were working on adding double digit addition, they started the week with double digit addition with no regrouping. As the week progressed, they began working on double digit addition with regrouping. I highly recommend these two resource packets: 






For students who were working on adding to 10, they started the week adding to five. As the week progressed, they began adding to 10. I highly recommend this resource packet:
