Lesson 1
Number Task
LO: To know how to find the volume of a cuboid.
Reminder:
Last week, we looked at finding the volume of shapes by counting cubes. However, there is a formula we can use to help us.
Volume = length x width x height
Task 1
Use the formula to work out the volumes of these cuboids.
Volume = length x width x height
(Remember your units will be cm3)
Task 2
Hint: Make all the units into cms.
1m = 100cm
10mm = 1 cm
Task 3
The volume of this cuboid is 32cm3. Calculate the height.
Hint: Use algebra to help.
32 = 4 x 2 x ?
Work out ?
Lesson 2
Number Task
1) The diameter of a circle is 22cm. What is its radius?
2) What is the median of these numbers: 3,2,5,2,6,4,1?
3) A triangle has a length of 5cm and a height of 6cm. What is its area?
4) Write 1521 in roman numerals.
5) ¼ of 20 = 0.25 of 40 = 25% of 60 =
Task 2
What is the difference between a regular polygon and an irregular polygon?
What does parallel mean?
What does perpendicular mean?
Can you remember the arm movements to parallel and perpendicular?
Task 3
For each of the triangles, quadrilaterals and polygons, answer the following questions:
Lesson 3
Number Task
1) What do the angles total in a triangle?
2) What is the mode of these numbers: 3,2,5,2,6,4,1?
3) Find the prime factors of 75.
4) 3 ½ - 2/5 =
5) Find: 10% of 250 20% of 250 50% of 250
LO: To know the names and properties of 3D shapes.
Reminder:
A 3D shape has three dimensions.
Face = A face is a 2D shape that makes up a 3D shape.
Edge = An edge is where two faces meet (sides).
Vertex = A vertex is the point where 3 or more edges meet (corners).
Here is a Cube.
It has 6 square faces.
It has 12 edges.
It has 8 vertices.
Task
Write down the name of each 3D shape.
Write how many faces it has.
Write how many edges it has.
Write how many vertices it has.
(Try to find the shapes at home to help you.)
