BIG IDEA 1 Develop quick recall of multiplication facts and related division facts and fluency with whole number multiplication. 6 x 7 = 42 42 ÷6 = 7 438 X 25

Teaching For Depth

MA.4.A.6.1 Use and represent numbers through millions in various contexts, including estimation of relative sizes of amounts or distances.

Magnitude of a Number When is 1000 a large number? When is 1000 a small number? When is 1,000,000 a large number ? When is 1,000,000 a small number?

PLACE VALUE is a fundamental feature of our number system. A thorough understanding of place value developed early through concrete experiences, is necessary in order for students to achieve computational fluency.,
