Turtles (Year 5 Maths) 2019 - 2020
Although based in Sand Dollars, Year 5 study maths separately to the year 4s with Mrs Tee in the Turtle class. We are proud to share our learning here. Keep checking for updates to resources and our gallery at this time.
School Closure Information
Turtles have access to a range of home learning offered by certain sites. Their logins are in their maths and class exercise books they brought home in March. They will need use of a laptop, PC, internet linked phone or tablet to access these resources. For those that are not on line there are paper resources to complete. Please feel free to email me if you need more dropped off at home. Best wishes to all at this time. Mrs Tee
Home Maths Lesson
Ideally your children need to do a maths lesson every day to keep recalling their number facts and learn new concepts. Each week the children can log in to the website and on their dash board see the work posted for them.
Under the homework tab they will be able to see
1)a zip folder labelled "Year 5 Maths for week .....". This will have all of the following inside:
- a powerpoint file of 5 lessons covering three objectives from the National Curriculum
- a teaching guide or notes to parents (unless the powerpoint has videos embedded to explain)
- any additional worksheets, diagrams or other work I want them to do
2) a folder labelled "Year 5 Maths Homework for week......" This will have one of the following inside:
- a worksheet for completion
- a set of activities for them to choose as they wish
- a website to investigate
- a target for calculation to help them speed up their maths
Under the discussion tab they will be able to see:
3) a discussion labelled "Year 5 Maths for week.....On this they can do any or all of the following:
- discuss the maths for the week
- post answers
- ask questions
- ask for extra work if they have found things too easy
- ask for extra work if they found the work too hard
- talk to each other about their leaning
- share any great new games, sites or ideas for future lessons they may have
- just say hi to all of us that miss them
A suggested home lesson might look like this:
5 minute starter : game/warmup activity from teh powerpoint
20 mins of a maths powerpoint lesson from the particular day (they are labelled Monday - Friday)
20 minutes of practice on the topic of work using activities form the powerpoint or games and activities from classroom secrets/purple Mash / something of their choice
5 mins of marking and uploading their work to their scrapbook or adding to that week's class discussion
If the internet is down feel free to practice a key maths skill, play a game using maths or watch a BBC bitesize lesson on the TV. Press the red button and then move to BBC bitesize. Open up for an age specific lesson that includes maths, reading and then a history/geography/science task. Check it out!

Homework for 4th May Week
Some people are having trouble with the homework download yesterday. This week you need to practice the first four of ten top tips to speed up your maths and then post in the discussion how you got on. I will post some of the others for next week. Try these:
10 tricks for doing fast math
These will help you to mentally calculate quickly in your head. I have given you 4 rules to practice this week. Pick one of the rules and practice on some numbers jot down the answers and then check after with a calculator or written method. You can challenge me then when we are back at school!
1. Adding large numbers
Adding large numbers in your head can be difficult. This method shows how to simplify this by making all the numbers a multiple of 10. Here is an example:
644 + 238
Rounding them up will make them more manageable. So, 644 becomes 650 and 238 becomes 240.
Now, add 650 and 240 together. The total is 890. But how much more or less than the original numbers did you add?
650 – 644 = 6 and 240 – 238 = 2, so we added 8 more…
To find the answer to the original equation, 8 must be subtracted from the 890.
890 – 8 = 882
So the answer to 644 +238 is 882.
2. Subtracting from 1,000
Here’s a basic rule to subtract a large number from 1,000: Subtract every number except the last from 9 and subtract the final number from 10
1,000 – 556
Step 1: Subtract 5 from 9 = 4
Step 2: Subtract 5 from 9 = 4
Step 3: Subtract 6 from 10 = 4
The answer is 444, easy!!
3. Multiplying 5 times any number
When multiplying any number by 5 there is a quick way to find the answer.
For example, 5 x 4 =
- Step 1: Multiply by 10, rather than 5
- Step 2: Halve your answer
10 x 4 = 40, half of 40 is 20.
4. Division tricks
Here’s a quick way to know when a number can be evenly divided by these certain numbers:
- 10 if the number ends in 0
- 9 when the digital root is 9. Remember the digital root is the sum of all the other digits:
81, digital root is 8 + 1 = 9
342, digital root is 3 + 4+ 2 =9
774, digital root is 7 + 7 + 4 = 18 and then 1 + 8 = 9
- 8 if the last three digits are evenly divisible by 8 or are 000
- 6 if it is an even number and when the digits are added together the answer is evenly divisible by 3
- 5 if it ends in a 0 or 5
- 4 if it ends in 00 or a two digit number that is evenly divisible by 4
- 3 when the digits are added together and the result is evenly divisible by the number 3
- 2 if it ends in 0, 2, 4, 6, or 8
