PLACE VALUE

2.)

3.) Round the number 324,678 to the nearest ten thousand.

This number will round to 320,000 because it is closer to 320,000 than 330,000.

Topic B: lessons 5-6

Topic C: lessons 7-10

Topic D: lessons 11-12

Ex 1: Sarah has \$445 in the bank.  Bob has \$200 more than Sarah.  Draw a tape diagram to illustrate Bob and Sarah's money.

Ex 2: How much money do Bob and Sarah have all together?

445 + 445 + 200 = \$1090

Ex 3: Estimate how much money Bob and Sarah have together (round to the nearest ten).

450 + 450 + 200 = \$1100

Yes, my answer is reasonable.  It is only \$10 away from the estimate.

TAPE DIAGRAMS-subtracting

Ex 1: A stadium has a total of 9,520 seats.  450 of the seats are in the shade.  Draw a tape diagram to illustrate.
