  1. Math Warm Up –Unknown Quantity10 minutes Draw a straight line to all the prime numbers 5 49 4 Draw a crooked line to all the square numbers 11 25 Draw a thick line to all the factors of 25 9 2

  2. Math Warm Up –Story Problem10 minutes Look at the problem 278 x 38 = Estimate the product Show your work using words, numbers, and/or pictures 278 x38 is close to_______

  3. Objectives • Content Objective • I See connection between multiplication and division problems • I will be able to solve division problems with 2 digit divisors • Language objective: • I will be able to explain to a partner how I can use a division problem to help solve a multiplication problem and in reverse. Ex. 120 ÷ 20 = 6 so 6 X 20 = X

  4. Vocabulary to Know Dividend-the number being divided Divisor-the number you are dividing by Quotient-the answer in a division problem 88 ÷ 4 = 22 22 488

  5. Division Notation Let’s review some steps to doing long division using both standard and big 7

  6. Hazel the chipmunk was gathering acorns to make her end of summer acorn bread. If each loaf of bread needs 12 acorns and she gathered 640 acorns then how many loaves could she make? Solve with Big 7 Solve with Standard Algorithm 100, 10, 5, 2, 1 D M S Ch B 53 r 4 3 5 r 4 640 12 -240 12 640 20 x 12 400 -60 -360 30 x12 0 4 40 -36 - 36 3 x 12 4 4 Objective: I will find a strategy that works to solve 2 digit by 2 digit multiplication

  7. Practice Let’s go over some division review and then you will get to work with a partner on solving the problems If you get done then play a game of Remainder Raccoon Today students will be able to solve long division problems

  8. Exit Ticket Write all the factors for 36 Be sure to show how you found it Today students will be able to solve long division problems

  9. SELF REFLECTION(In Math Journals) Today students will be able to solve long division problems
