Math! Math! Math!
This week, mathematicians will multiply by multiples of ten (3.NBT.3) on the place value chart. Place value understanding helps them to notice that the product shifts one place value to the left when multiplied. In the subsequent lesson, place value understanding becomes more abstract as students model place value strategies using the associative property (3.NBT.3, 3.OA.5). 2 × 30 = 2 × (3 × 10) = (2 × 3) × 10. The final lesson focuses on solving two-step word problems involving multiples of 10 and equations with unknown quantities (3.OA.8)
