Choose a number and describe Some of its properties. It is an even number It has two tens It has four ones It is in the 2 x tables What number is it? Try this with a few different numbers Multiplication Using a method of your choosing, solve this number sentence Using Percy sing the 2/5/3/4/10 x table https: //www. youtube. com/watch? v=A 8 c. Cy. QTk. R g. I Today we are going to look for number patterns. Multiplication Look at these multiplication number sentences 2 x 10= 20 4 x 10= 40 6 x 10= 60 3 x 10=30 5 x 10=50 7 x 10=70 Key Q; what patterns can you see? Example; First column going up in two’s Second column always the same number Third column going up in 20’s Anything else? all answers are in the 5 x table and ten times table Multiplication Level 1 2 x 5 = 10 4 x 5 = 20 6 x 5 = 30 1 x 5=5 3 x 5 = 15 5 x 5 = 25 looking at each column write down what patterns you have identified column 1; column 2 Level 3 2 x 5 = 10 4 x 5 = 20 6 x 5 = 30 1 x 5=5 3 x 5 = 15 5 x 5 = 25 2 x 5 = 10 6 x 5 = 30 10 x 5 = 50 2 x 2= 4 4 x 2= 8 6 x 2= 12 1 x 2=2 3 x 2=6 5 x 2=10 Use the information above to find a pattern and solve the questions below. looking at each column write down what patterns you have identified column 1; column 2; Column 3; Challenge; when you multiply 5 by an odd number what do you notice about the ones digit? 14 x 5 = ? 18 x 5 = ? 1 x 5=5 5 x 5 = 25 9 x 5 = 45 13 x 5 = ? 17 x 5 = ? Explain in your own words the pattern you found how you would solve the following: 30 x 5 = ? 25 x 5 = ? Greater Depth Challenge Tom said the 20 times tables is easy it’s like the 2 x table. Explain what he might mean using examples. Visualisation Imagine a box of 10 p and 5 p coins. In the box there are eight 10 p coins and four 5 p coin. As I add coins and take out coins, work out the money in my box. I add 10 p and another 10 p. How much ? I take out a 5 p and a 10 p , how much?
