Minilessons for Multiplication and Division
A warm–up mental math string 100 x 13 2 x x x x x 34 What strategy does this string support? What big ideas underlie this strategy?
Pictures for early multiplication
Small Group Discussions What strategies would you expect to see? How would you represent them?
Count by ones Skip count 2 x 6 = 4 x 3 = 6 x 2 2 x 9 = 2 x 3 x 3 = 6 x 3 Associative property How many apples? How many lemons?
How many tiles in each patio? The furniture obscures some of the tiles possibly providing a constraint to counting by ones and supporting the development of the distributive property
The Landscape of Learning
Lets go to a classroom… Cdrom, minilesson folder (first), 3 rd page Video clip #53
Did anyone try minilessons like these, with pictures? Did you find any nice pictures in magazines that you could use?
Heres one that I found.
Grade 4 6 x 8 12 x 8 12 x 4 24 x 2 3 x x 50 Whats the focus of the string? A) doubling and halving B) associative property C) distributive property D) using friendly numbers
How could you show doubling and halving strategies on an array?
Lets go to a classroom… Cdrom, minilesson folder (first), 1 st page Video clip #16
Grade / / / / / 17 Whats the focus of the string? A) distributive property for multiplication B) partial quotients C) simplifying D) A and B
For the last problem, 323/17, if a child said I got 19 because I took 17 away from 340, how would you represent that using an open array?
Lets go to a classroom… Cdrom, minilesson folder (second), 3 rd page Video clip #330
Has anyone tried a minilesson like this? Any struggles with representing?
Grade / / / / / / / 18 Whats the focus of the string? A) distributive property B) simplifying C) splitting D) using landmark numbers
How does this string help with fractions?
