There will be a test next Tuesday on metrics and customary units. Students are working on ratios and using them to convert units of customary measure. They need to remember the mnemonic "King Henry Dies By Drinking CHocolate Milk." This reminds them of the order of metric units. They need to know that you begin with the units that you are given and move your decimal point the number of units given in the same direction. The B stand for the basic units which are grams, liters and meters. This means that if you are given 7.9mg and want to change it to grams...grams are 3 units to the left so we will move the decimal 3 units to the left and get.0079
Students also made a chart of customary units. They need to remember that there are 8 oz. in a cup...2 cups in a pint, 2 pints in a quart and 4 quarts in a gallon. Using their knowledge of unit rates, the should be able to convert measures such as 6 pt. = ____ c. by creating a ratio that shows 1 pt. has 2 cups ; therefore we multiply 2 x 2 to find the number of cups in 6 pints. Remember - when you are moving from a smaller unit to a larger one you divide. When moving from a larger unit to a smaller one, you multiply! Homework tonight is practicing these skills in their workbooks unit 7-7 Practice (evens).

With less than 2 weeks to go, I can't believe how fast the school year has gone by. The students have learned a great deal of math and I am so proud of them! I told them in class today that learning will continue through the end of school and I expect good attendance and behaviors from them. We finished our solids unit and I know some of it was difficult for them, but they are shining so far as they learn about ratios and proportions. They are practicing practical applications of proportions and doing very well. We continue this week (except Thursday - field day). by covering the metric system and doing conversions. After this we will touch on customary unit such as cups, pints, quarts, gallons etc. Next weewk we will look at scale drawings. There will still be HW's a quiz and one more test. We will stay focused and I'm sure they will all do well.

We've completed our unit on solids.Surface area gave everyone a hard time so we will re-visit it at a later date.
This week we began studying ratios and proportions. A 'Proportion" is an equation that shows that two ratios are equivalent. To determine if a pair of ratios form a proportion, you can cross multiply. If the cross products are equal, then the ratios form a proportion. You can also use cross multiplication to solve proportions. 1. Write the cross products of the 2 ratios. 2. multiply 3. Divide.
3 = 12
____ ____ 32 x 3 = 96
x 32 96 divided by 12 = 8 so x = 12

HW Thurs. 5/3 worksheet #2 solving proportions
