Statistics Week 5 Year 6 Miss Sutherland Miss

Statistics Week 5 Year 6 Miss Sutherland, Miss Church and Miss Moore

Happy Monday! We hope that you’re all doing ok and staying safe at home. Over the next two weeks in maths we will be looking at statistics, including line graphs and pie charts. Well done for getting this far! Thank you to everyone who has sent their work in, it is looking great. Remember to try your best this week and keep sending your work back. We miss you all and hope to see you soon.

This week in maths we will be looking at statistics by using pie charts. Monday: Properties of a circle Tuesday: Read and interpret pie charts Wednesday: Pie charts with percentages Thursday: Find the mean Friday: Arithmetic

Monday 18 th May L. O: To name the properties of a circle

Task 1 – Timetables This week we will go back through our 12 s https: //www. youtube. com/watch? v=PABb 8 Hhmte. M

Quick Fire Tables See how quick you can answer the next 14 questions- time yourself to see if you can get quicker each day.

Quick Fire Tables 12 x 2 = 4 x 8= 12 x 8 = 10 x 6 = 12 x 6 = 11 x 7 = 7 x 12 = 9 x 4= 9 x 12 = 8 x 6= 11 x 12 = 10 x 12 = 12 x 6 = 7 x 7=

An important property of a circle is that: The radius is half the length of the diameter. In other words, the diameter is double the length of the radius. We can now use those important skills of doubling and halving! If the radius of this circle is 5 cm How long is the diameter? The diameter is double the length of the radius. 5 x 2 = 10 Therefore, the diameter = 10 cm

Now, your turn ! Remember: The radius is half the length of the diameter. In other words, the diameter is double the length of the radius. 12 cm

Well done for getting this far! If you are not yet confident, please go back through the last couple of slides. If you are feeling confident, you are now ready to move onto some problem solving.

Reasoning 1 Jemima says, If the radius of a circle is 95. 5 mm then the diameter must be 190 mm. Is she correct? Explain your answer. Jemima is not correct because the diameter is always double the length of the radius, so it would be 191 mm. © Classroom Secrets Limited 2018

Now go through the practice questions on the school’s website. This week, please try to complete 6 to 8 of these questions. Remember they are different levels so do the ones that are manageable to you.
