Today for MaTh I idea I would create something alongside candy : )
So CCSS 3.NBT.A.3 states: Multiply one-digit whole numbers yesteryear multiples of 10 inward the make 10–90 (e.g., nine × 80, five × 60) using strategies based on house value as well as properties of operations.
So, hopefully your 3rd graders know their times tables for this i because they volition demand to know the i digit nine x 8 easily to create nine x 80. If yous kids demand a piddling assistance alongside those yous mightiness consider purchasing my conceptual multiplication cards. They tin assistance your visual learners
To visually exhibit a problem, kids demand to empathize that multiplication is actually almost groups. In my carte du jour higher upwards yous meet that iii x half dozen is actually iii groups of half dozen or yous tin exhibit it every bit half dozen groups of iii also.
So, for my activeness to create alongside this criterion I position together a house value arrangement alongside candy corn. In the ones house nosotros convey the private candy corn, the tens house nosotros convey them inward bundles of ten, as well as hence for the hundreds house nosotros convey a bowl of x bundles. I could become on as well as brand a thousands house which would in all probability endure a handbasket to grip x bowls.
So, I did a sample occupation 4 x 20. How many ways tin nosotros approach this? Some children mightiness know how to create it on newspaper alongside 4 x 0 is 0 as well as 4 x 2 inward the same column is 8, hence it is fourscore (but create they empathize it conceptually?). Do they know they tin correspond it every bit 4 groups of twenty or twenty groups of 4.
If the kids exhibit it they volition see...
Of those ii ways, which agency is easier to show? Why?
Most probable yous volition concord that 4 groups of twenty is easier to show. With the twenty groups of 4 it is at that topographic point adds an additional setp to figure it out. Multiply the array 4 x five as well as and hence multiply that yesteryear the pieces of candy. (4 x 5) x 4 however is 80. They merely constitute the factors of 20.
BTW, yous tin create this alongside other things if yous don't convey or desire kids having candy: grapes, raisins, beans, beads, or something else. Do yous e'er role non-standard manipulative to create math inward your class?
