I’m looking for professional development ideas around building teacher knowledge and confidence in teaching elementary math CCSS to students. Our teachers need help in focusing on developing students understanding of math, not automaticity in completing algorithms. Any ideas?
You can use various teaching aids for the students to help them with better understanding.
One area our students had a hard time understanding was multiplying and dividing fractions. Our students understood the method, but did not understand why it worked. To help them, we used area models on transparencies to help them understand what was happening to the pieces. Students were able to draw and color each fraction. When the pieces were overlapped it helped students physically see the answers. Eventually we moved onto paper. This video explains what students do using paper. https://www.youtube.com/watch?v=hhMztpnKxvQ
Hope this gives some ideas!
