At my current school we started our unit on fact families today with a lesson on commutative property using the SMART board. At workshop students were able to draw a card and create addition sentences based on that card using manipulatives and a work mat. Tomorrow we will be creating fact family maps during math explorations.
Students drew a card and counted out that number of shapes onto the top of the plate. They then split up the number of shapes into the two separate sections on the plate. They then created addition sentences using the commutative property of addition. Here you see a student making 4 + 2 = 6 as well as 2 + 4 = 6.
Student’s would then draw another number and complete the whole process over again. This student drew the number 4. The addition sentence on the paper was from her previous number that she drew which was 5.
For spiral review in math workshop we had number / quantity review, patterns, building shapes using smaller shapes.
If you notice on the first picture students were building a hexagon base by stacking two trapezoids next to each other on top of the hexagon. Geometry in common core requires students to use those critical thinking skills by being able build bigger shapes with smaller ones. Students used lily pads to put the number of counters on that lily pad that matched the number. In the last picture a student was creating an AABB pattern.
