Applying our understanding of times table

Filed Under (General News) by on 10-01-2018 and tagged , , , , , , , ,

Today we are going to show that we know our times tables and can apply that knowledge to more complex calculations.

Use comments to answer the calculation and then explain how you have used your knowledge of times tables to solve it.

÷

Have a look at this and have a go!

I have investigated the pattern made by the digit in the ones place in the TWO times table and found this

2, 4, 6, 8, 0, 2, 4, 6, 8, 0, 2, 4 ….. and so on

Explore other multiplication tables to find the patterns that are created in the ones place.

Comment on your findings!

    60×2=120
    I worked out this answer by doing 6×2=12 and then add on a 0 because 60 Is 10 more than 6.

    30×2=60 I know my 2 times table so I did 30+30 which eaquels 60 because in you 2 times table you just need to double the number and you will get your answer.

    10×2=20 I know this because when you see this sum you can replace the one with the two and you come out with a 20

    70×1=70
    I worked this out
    by using my 7 times table
    I know that 7×1 =7 so add a
    zero on the end it will become 70.

    60×2=120
    I worked this out by using my 6x tables I know that 6×2 = 12 so if I double it ten times then I will get 120

    30×2=60
    I worked out this answer by doubling 30. This shows my
    knowledge of my 2 times table.

    60×2=120 I did 6×2=12 so then I got the zero from 60 and put the zero at the end. My answer was 120.

    I know that the 9x table has a pattern because when you get to 45 the numbers were swapped around.

    5,10.15,20, 25, 30

    the pattern in the 5 x table is 5, 0, 5, 0 and so on.

    Wow, you have used some great strategies. Can you explain why using a strategy like the ones you have described is more efficient than trying to work it out from the original sum?
    Don’t forget to use the word because when you are explaining.
