Numeracy Focus – 2D and 3D Shape and Measures


This week’s focus is on the area of shape. The children will revise the names and properties of 2D and 3D shapes before moving on to calculating area and perimeter (2D shapes) and estimating volume (3D shapes). Remember we do not expect parents/guardians to print tasks, a notebook is fine for jotting down answers.


Daily Timetable for Numeracy Lessons

Mathletics 15 mins

Times Table Rockstars 5 mins

Mental maths game/task 10 mins

Task 30 mins

PowerPoints/videos/games to try before completing the task can be found under your child's step. 


Learning Focus

In preparation for their Friday test, the children will need to continue to revise the following times tables: 

Group 1 – x4 and divide by 4

Group 2 – x9

Group 3 - mixed x2 to x12 and associated division facts



The children will complete their UR Brainy task for their mental maths. Today the children will revise the names and properties of 2D and 3D shapes. There are two PowerPoints for the children to scan through along with a poster to revise the names of triangles. Remind the children that if the shape is irregular, they need to count the number of sides and label it as an irregular_______. For example an irregular 7-sided shape is an irregular heptagon.


·         Step 1 – Complete questions 1-14

·         Steps 2 & 3 – 1-24  


The children will revise rounding numbers in their mental maths game. Today the children will revise finding the area of squares and rectangles. Step 2 and 3 children will use the formula ‘length x width’ while Step 1 children will count the squares inside the shape. Ensure that Step 3 children have a pencil and a piece of paper to complete their multiplying. Remind the children that area is measured in cm/m squared e.g cm2. There is a PowerPoint for the children to study before completing their task.




Today the children have their next UR Brainy task for mental maths. The children are revising what they know about finding the perimeter of a shape. There is a PowerPoint to revise that perimeter is the distance around the outside of a shape. The children then have a task to complete. Remind the children to label each side of the shape first before adding their measurements.



For mental maths the children have a game to complete, matching fractions and decimals. Step 1 children will revise what they know about area and perimeter before calculating the area and perimeter of squares and rectangles. Children can use the PowerPoints from Tuesday and Wednesday to revise how to find the area (counting squares inside) and perimeter (adding the measurements around the outside of the shape). Step 2 and 3 children are learning how to find the area of compound shapes (2 rectangles placed together) by splitting the shape first before finding the area of each rectangle and then adding them together to find the area of the entire compound shape. There is a PowerPoint for the children to try first.


Step 2 & 3 children – when finding the area of the shape without the shaded rectangle, the children need to find the area of the smaller shaded rectangle and the larger rectangle. Once complete they need to subtract the area of the shaded rectangle from the larger rectangle. For example - area of shaded rectangle = 3 x 5 = 15m2, area of the larger rectangle = 12 x 10 = 120m2. Area of the unshaded rectangle = 120 - 15 = 105m2. 


Today the children are revising how to calculate the volume of 3D shapes. There is a PowerPoint for the children to revise our strategies before completing their task.


  1.  Counting the number of cubes in the first layer and multiplying it by the number of layers
  2. Using our formula length x depth x height

Remind the children that volume is measured in cm cubed = cm3.

Friday Test 

The Hit the Button link can be found in the children’s steps to test their times tables. The children's Friday test maths questions can also be found under each step.
