Science
On Friday we talked about CHEMICAL changes. What are some signs of a chemical change?
explosion
light
heat
new substance
gas
colour change
combustion (burning)

Chemical changes are irreversible. You cannot get the original material back.

Examples of Chemical Changes

• Burning wood
• Souring milk
• Mixing acid and base
• Digesting food
• Cooking an egg
• Heating sugar to form carame.
• Baking a cake
• Rusting of iron

On Monday we will be observing a chemical change involving the reaction of baking soda and vinegar.

We also touched on THE LAW OF CONSERVATION OF MASS.

Be prepared to complete your investigation Monday morning.

DIFFERENT MEANINGS OF MULTIPLICATION: Example 7 x 3 = 21

Equal Groups:

Repeated Addition:

7 + 7 + 7 = 21            or         3 + 3 +  3 +3 + 3 + 3 + 3 = 21

Skip Counting:

7, 14, 21

3, 6, 9, 12, 15, 18, 21

Array:

XXXXXXX            XXX

XXXXXXX            XXX

XXXXXXX            XXX
                                XXX

                                XXX
                                XXX

                                XXX

Word Problem:

Mr. Morson bought 3 packages of gum. Each package had 7 sticks of gum. How many sticks of gum did he buy?

FAMILY OF FACTS: Example 3, 7, 21

3 x 7 = 21

7 x 3 = 21

21÷ 3 = 7

21÷ 7 = 3

RELATING MULTIPLICATION AND DIVISION FACTS:

Example: How can you use 6 x 4 = 24 to find 6 x 8?

6 x 4 is 4 groups of 6, so 8 groups of 6 is double 4 groups of 6

6 x 8 = 24 + 24 = 48

Example: How can you use 36 ÷ 6 = 6 to find 36 ÷ 3?

36 ÷ 6 is dividing 36 into 6 equal groups, 36 ÷ 3 is dividing 36 into 3 equal groups so there should be twice as many in each group.

36 ÷ 3 = 6 + 6 = 12

SOLVING PROBLEMS:

·         There are 27 students. There are 3 students in each group. How many groups are there altogether?

·         There are 6 eggs in 1 carton. How many eggs are in 3 cartons?

·         Chad bought 2 books at a yard sale. His brother, Sam, bought 3 times as many books. How many books did Sam buy?

·        Colin has 24 markers. Andrea has 6 markers. How many times as many markers does Colin have than Andrea?

·        Micha also earns $7 a week doing chores. She earned $63 altogether doing chores. For how many weeks did she do chores?

·        Create a division word problem using 63, 9

·        Create a multiplication word problem using 6, 7

 Grade 5 Test #1

RELATING MULTIPLICATION AND DIVISION FACTS:

Example: How can you use 6 x 40 = 240 to find 6 x 80?

6 x 40 is 40 groups of 6, so 80 groups of 6 is double 40 groups of 6

6 x 80 = 240 + 240 = 480

Example: How can you use 360 ÷ 6 = 60 to find 360 ÷ 3?

360 ÷ 6 is dividing 360 into 6 equal groups, 360 ÷ 3 is dividing 360 into 3 equal groups so there should be twice as many in each group.

360 ÷ 3 = 60 + 60 = 120

2 DIGIT / 3-DIGIT BY 1-DIGIT MULTIPLICATION:

Example: 543 x 6 (Expanded form and algorithm)

Example: 67 x 8

SOLVING MULTIPLICATION PROBLEMS:

Ava bought 5 boxes of 62 pens and Luca bought 6 boxes of 53 pens. Who bought more pens? How many more?

Create a word problem using 512 x 9

Use 17 x 9 to finish each word problem

A rectangle has….

Each soccer team has ….

ESTIMATING PRODUCTS AND QUOTIENTS:

There are 72 pens in a box. About how many pens in 8 boxes?
There are 351 erasers for 6 classes. About how many erasers are there for each class?
