P6 Numeracy 23rd February

Decimals - tenths Lesson 6

It's time to look at division. Can we avoid having a remainder at the end of our calculations?

Warm-up activity

This week's focus is on our multiplication and division facts so it's time for Day 2 of our Numeracy Ninja challenges!  Every day this week we are going to complete a Numeracy Ninja challenge where all the tables have been mixed up and it is your job to work out the missing number in each calculation.

There are 60 questions to complete each day.


Don't forget to time yourself to see if you can beat yesterday's time!  If you haven't finished after 15 minutes, stop and spend another 5 minutes revising your tables please.

If you choose the higher level challenge, you are looking at all the tables from 2 X to 12 X plus their division facts.

Today's lower level challenge focuses on the 3 X table.  Download the Multiplication Tables Factsheet and spend a couple of minutes practising counting forwards and backwards in 3s and looking at the related division facts.  Then download the 3 X table challenge and try to complete it without any help.  Lots of questions are repeated throughout the worksheet to help to reinforce your learning.

Main activity

In our work on decimals, we have been looking at tenths and practising adding, subtracting and multiplying.  Today we are going to learn how to divide using decimals. This will mean that we will no longer have a remainder at the end of our calculation

e.g. if I was working out 93 ÷ 5

 would become


Watch today's video where Mrs Bell looks at some examples and then download one of the activities below.  You will be completing some of your questions mentally and then doing a written calculation for the remaining questions.  Use the Division Facts handout if you need some help with your dividing and you can also download a squared page for writing out your calculations.


Your final questions are about dividing by 10.  As we learned before Christmas, when we divide by 10, each digit moves one place to the right so the number that was in the tens column moves to the units, the number that was in the hundreds column moves to the tens, etc.

          Th H T U                 Th H T U

e.g.             7 0    ÷ 10 =                7

                1 8 0    ÷ 10 =             1 8

             2 4 5 0    ÷ 10 =          2 4 5


When dividing a decimal number by 10, the same rule applies so the digit that was in the units column moves into the tenths.  We DO NOT move the decimal point!

           Th H T U . t                   Th H T U . t

e.g.                 5 . 0      ÷ 10 =               0 . 5

                    3 6 . 0      ÷ 10 =               3 . 6

                 5 7 8 . 0      ÷ 10 =            5 7 . 8

              4 9 3 6 . 0      ÷ 10 =         4 9 3 . 6

Reasoning activity

Today's reasoning asks you about perimeter!
