Autumn and I explore multiplying 6×7, 7×7, 8×7, etc. using unit math, that is, by starting with the conversion “6 sevens = 42 ones” and using that conversion to understand 7 sevens, 8 sevens, and so on. This video shows the power of unit math thinking and why Eureka Math’s PK-5 curriculum is called, “A Story of Units.”
At the end of the video, we just go crazy and figure out some multiplications and divisions just for fun! Enjoy Autumn’s struggles and cute expressions throughout.
