Performance objectives

• Recall multiplication facts for 2, 3, 4, 5, and 10.
• Recall division facts for 2, 3, 4, 5, and 10.
• Solve simple word problems using these facts.
• Identify patterns in multiplication tables.

Lesson summary

This week, we're diving deeper into multiplication and division! Knowing our multiplication and division facts for 2, 3, 4, 5, and 10 is like having a superpower in maths. It helps us solve problems quickly and easily, whether we're sharing sweets with friends, counting our pocket money, or figuring out how many rows of seedlings to plant in our garden. These facts form the building blocks for more complex maths later on, so it's super important to master them now!

Think about it: knowing your multiplication tables can help you quickly figure out how many bread rolls to buy for your family's braai!

Lesson notes

Multiplication: Multiplication is a quick way to add the same number multiple times. It's like having a shortcut! The 'x' symbol means "times."

Example: 3 x 4 means adding 3 four times: 3 + 3 + 3 + 3 =

1

2. Therefore, 3 x 4 =

1

2. The 2 times table: Multiplying by 2 is the same as doubling a number. Remember, all answers in the 2 times table are even numbers. 1 x 2 = 2 2 x 2 = 4 3 x 2 = 6 4 x 2 = 8 5 x 2 = 10 6 x 2 = 12 7 x 2 = 14 8 x 2 = 16 9 x 2 = 18 10 x 2 = 20 The 3 times table: This one can be a little trickier, but practice makes perfect! 1 x 3 = 3 2 x 3 = 6 3 x 3 = 9 4 x 3 = 12 5 x 3 = 15 6 x 3 = 18 7 x 3 = 21 8 x 3 = 24 9 x 3 = 27 10 x 3 = 30 The 4 times table: Notice that the 4 times table is double the 2 times table. 1 x 4 = 4 2 x 4 = 8 3 x 4 = 12 4 x 4 = 16 5 x 4 = 20 6 x 4 = 24 7 x 4 = 28 8 x 4 = 32 9 x 4 = 36 10 x 4 = 40 The 5 times table: All answers in the 5 times table end in either a 0 or a 5. 1 x 5 = 5 2 x 5 = 10 3 x 5 = 15 4 x 5 = 20 5 x 5 = 25 6 x 5 = 30 7 x 5 = 35 8 x 5 = 40 9 x 5 = 45 10 x 5 = 50 The 10 times table: This is the easiest one! Just add a zero to the end of the number you're multiplying by. 1 x 10 = 10 2 x 10 = 20 3 x 10 = 30 4 x 10 = 40 5 x 10 = 50 6 x 10 = 60 7 x 10 = 70 8 x 10 = 80 9 x 10 = 90 10 x 10 = 100 Division: Division is the opposite of multiplication. It's about sharing or splitting something into equal groups. The '÷' symbol means "divided by."

Example: 12 ÷ 3 means splitting 12 into 3 equal groups. Each group will have 4 in it.

Therefore, 12 ÷ 3 =

4. Understanding the relationship between multiplication and division: If 3 x 4 = 12, then 12 ÷ 3 = 4 and 12 ÷ 4 =

3. This is very important! It means if you know your multiplication facts, you also know your division facts!

Sharing equally: Imagine you have 15 marbles and you want to share them equally among 5 friends.

This is a division problem: 15 ÷ 5 =

3. Each friend gets 3 marbles.

Grouping equally: You have 20 sweets and want to pack them into bags of 4 sweets each.

This is also a division problem: 20 ÷ 4 =

5. You will need 5 bags.
