Levan Scott Academy Lesson Plan

EnVision Math Unit Lesson Plan Common Core Standards: Grade Level: Fourth Grade Topic 5: Number Sense: Multiplying by 1-Digit Numbers 4.NBT.3; 4.NBT.5; 4.OA.3

Instructional Emphasis: Number and Operations in Base Ten Essential Questions: Big Ideas:  How can you use arrays to multiply by 10 and 100?  5-1: Making an array with place-value blocks provides a way to visualize and find products. (5-1)  5-2: Basic facts and place value patterns can be used to find products when one factor is 10 or 100.  What place-value patterns can be seen when you  5-3: Making an array with place-value blocks provides a way to visualize and find products. A 2-digit by 1- multiply 1-digit numbers by multiples of 10 and digit multiplication calculation can be broken into simpler problems; a basic fact and a 1-digit number times 100? (5-2) a multiple of 10. Answers to the simpler problems can be added to give the product.  How can you break apart arrays to help you  5-4: There is more than one way to do a mental calculation. Techniques fro doing multiplication multiply with greater numbers? (5-3) calculations mentally involve changing the numbers or the expression so the calculation is easy to do  What are some ways to multiply mentally? (5-4) mentally.  How can you use rounding to estimate when you  5-5: Rounding is one way to estimate products. multiply? (5-5)  5-6: Answers to problems should always be checked for reasonableness and this can be done in different ways. Two ways are to us estimation and to check the answer against the question and conditions in the  How do you know if your answer is reasonable?
