MULTIPLICATION
Use this interactive hundreds chart to label some of your timetables on it using different colours. Do you see any patterns? Which time tables have patterns? What is the pattern like?
Now use the chart to count up by 4, 6, 7, 8, or 9! You choose which ones to practice first. Do you see the connection between counting up and a time tables?
Creative ways to learn your timetables:
Here is an interesting powerpoint you can access to help you learn how doubling works in the 4 time tables
4
If you know your 2 times table, you can do your 4 times table What is 4 x 6? To work it out, just ask yourself what 2 x 6 is instead, then double it to get the answer to 4 x 6. For example: 4 x 6 = ? Step 1: Just ask yourself what 2 x 6 is instead
Step 2: Double the answer to Step 1 above

6
If you know your 3 times table, you can do your 6 times table What is 6 x 8? To work it out, just ask yourself what 3 x 8 is instead, then double it to get the answer to 6 x 8. For example: 6 x 8 = ? Step 1: Just ask yourself what 3 x 8 is instead
Step 2: Double the answer to Step 1 above

8
If you know your 4 times table, you can do your 8 times table What is 8 x 7? To work it out, just ask yourself what 4 x 7 is instead, then double it to get the answer to 8 x 7. For example: 8 x 7 = ? Step 1: Just ask yourself what 4 x 7 is instead
Step 2: Double the answer to Step 1 above

Learn how to multiply with two 2-digit numbers |
Help creatures to line up and walk through gates. Make equal rows and columns. For example, start with 17 pobbles. Predict whether the number can be divided into an equal number of rows. If not, add or subtract pobbles to make a number that will work. Check your prediction. This learning object is one in a series of three objects.
Make equal rows and columns to explore how numbers can be broken up into factors. For example, the number 24 can be expressed as 12x2 or 2x12, and therefore, it can be divided equally using its factors 12 and 2. Identify a missing factor to complete a factor family. Solve four expressions: two multiplication and two division statements. This learning object is one in a series of five objects.
Explore how numbers can be broken up with factors. For example, the number 9 can be expressed as 9x1 or 3x3. Predict the factors of a number in the range 1 to 50. Make an array of equal rows and columns with the number to check its factors. Choose a statement to describe how many factors the number has. This learning object is one in a series of five objects.
Solve multiplications such as 9x88. Use a partitioning tool to help solve randomly generated multiplications. Learn strategies to do complex arithmetic in your head. Split a multiplication into parts that are easy to work with, use simple times tables, then solve the original calculation. This learning object is one in a series of five objects.
Factors and Multiples
ACTIVITY:
On a piece of paper use the equals sign (=) to record equivalent multiplications.
For example: 4 x 3 = 6 x 2 (because both equal 12).
Factor sentence: This means that 4, 3, 6 and 2 are all factors of 12 (you would find 12 in the 4 time tables, 2 time tables, 6 time tables and 4 timetables)
Now make 10 of your own and write them down! Then write their factor sentence under them.
1. 2 x 8 = 4 x 4 (both equal 16)
Factor sentence: 2, 8 and 4 are all factors of 16

Decide if these number sentences are True or False:
1. 2 x 2 = 4 x 1 True or False?
2. 8 x 5 = 10 x 6 True or False?
3. 8 x 8 = 4 x 16 True or False?
4. 7 x 2 = 7 x 2 True or False?
5. 3 x 8 = 6 x 4 True or False?

Lesson on Single digit division- problem solving step by step
Use a dividing tool to make equal shares of sweets. Complete a sentence describing a number operation. For example, 17 jellybeans shared equally into 6 jars. Predict how many sweets will go into each container and identify how many sweets are left over. This learning object is one in a series of five objects.
