4.6 Problem Solving: Interpret the Remainder (p.92-93)

When Solving word problems try the following strategies:
I. Try to make a picture of the situation in your head and draw or show important parts on paper in a way that organizes the information.
II. Make a model of the situation by using boxes or circles to represent groups and

Enjoy the celebration!

4.5 Divide Decimals by Decimals (p. 88-91)

I. Follow these steps for dividing a decimal by a decimal
1. Make the divisor a whole number by moving the decimal point to the right (this is like multiplying by 10 for each place you need to move the decimal place over).
2. Move the decimal point in the dividend the same number of places to the right that you moved it in the divisor.
3. Divide like you normally divide by a whole number
4. When you find the quotient, move the decimal point directly up into your answer from the dividend.
5. Check by multiplying the answer by the divisor. It should equal the dividend.

4.3-4.4 Divide Decimals by Whole Numbers

I. Use the following steps when Dividing a mixed number by a whole number
1. Divide as usual and be sure to KEEP THE PLACE VALUES LINED UP
2. Place a decimal point in the quotient (space for your answer) directly above where it is in the dividend (the value you are dividing)

Here's some info from Harcourt on how to divide decimals.

4.2 Multiply Decimals (p.80-83)

I. Multiply as if you were multiplying whole numbers (pretend there is no decimal while mulitplying)
II. Count the number of decimal places in the factors (the numbers you multiplied together)
III. Starting at the right of your answer, count over that number of spaces. That is where the decimal point will be placed.

Ex.
0.14 two spaces
x 7 zero space
----
0.98
