Maths Year 5 Spring Shape (A)

Day 1 Teaching
The cube and the cuboid. What is the same about these two shapes and what is different? Discuss how to sort 3-D shapes into the two sets of a Venn diagram. Show how a Carroll diagram can also allow us to sort shapes.
Group Activities
-- Describe and sort 3-D shapes according to a range of properties.

Day 2 Teaching
Look at pictures of 3-D shapes on suggested websites. Can children describe and name each shape? Do they find it easy to visualise shapes from 2-D drawings? Click on shapes to play animations. Explore the many different types of pyramid and prism.
Group Activities
Use the ‘Pharaoh’s rest’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
-- Explore the properties of prisms and pyramids.

• Models of 3-D shapes including cuboids, cones, cylinders, pyramids and prisms
• Feely bag, sorting hoops & small cards for labels
• Blu-tack & dry-wipe pens
• ‘Prisms’ & 'pyramids' activity sheets (see resources)
• Paper, scissors, tape
• Models of prisms & pyramids

Suggested for Day 1
Find lines of symmetry (simmering skills)

Suggested for Day 2
Bonds to 100 (simmering skills)

Day 1
Sort 3-D shapes according to number of faces.

Day 2
Sort 3-D shapes according to number of edges.

• Always true, sometimes true or false?
  A cube is a type of cuboid
  Pyramids have 5 faces
  Prisms have a cross-section that is always the same, so a cylinder is a prism
  Cubes and cuboids have the same number of vertices
• How many edges has a…
  -- Cuboid?
  -- Square-based pyramid?
  -- Cylinder?
  -- Triangular prism?

In-depth investigation: Pharaoh’s Rest
By looking at this net for a square-based pyramid, can you visualise and draw other, different nets that fold to give the same pyramid?

What’s Special?
Identifying and describing properties of triangles; using these properties to sort the triangles.

Day 1 Teaching
Display ‘Guess the shape’. Choose a shape. Children work in pairs to write five facts about it. Take feedback. Ensure that children are clear that a polygon only has straight sides, so a circle, oval, semi-circle are 2-D shapes, but are not polygons.

Group Activities
Draw and investigate polygons on isometric paper.
-- Play ‘Guess the shape’ to practise describing 2-D shapes.

Day 2 Teaching
Ask children to draw a polygon. Make sure all children draw a straight-sided closed shape. Ask children to hold up their polygon if it has an acute angle. Continue like this, asking children to hold up their shape if it has a particular property.
Group Activities
-- Draw polygons of 3 to 8 sides, with certain features stipulated.

Day 3 Teaching
Ask children to draw a quadrilateral, then discuss similarities and differences. Repeat, to explore other properties by drawing a quadrilateral with at least one pair of perpendicular sides/ parallel sides, etc. Name and explore the different quadrilaterals using an online activity from www.mathsisfun.com.
Group Activities
Use the in-depth problem-solving investigation ‘Quadrilaterals’ from NRICH as today’s group activity.
Or, use this activity:
-- Draw, describe and classify quadrilaterals.

• ‘Guess the shape’ sheet (see resources)
• Rulers & squared paper
• ‘Five-triangle polygons’ sheet (see resources)
• Protractors, scissors & glue
• Poster paper (7 sheets)
• ‘Exploring quadrilaterals’ sheet (see resources)

Suggested for Day 1
Times tables (simmering skills)

Suggested for Day 2
Place numbers with 2dp on a line (simmering skills)

Suggested for Day 3
Place value in 4-digit numbers (simmering skills)

Day 1
Look at properties of 2-D shapes.

Day 2
Look at properties of polygons.

Day 3
Look at properties of quadrilaterals.

• Is a semicircle a polygon?
  Draw a polygon and list five of its properties.
• Which of these shapes are quadrilaterals (see download)?
  

In-depth investigation: ‘Quadrilaterals’
How many different quadrilaterals can be made by joining four of the dots on a circle with eight evenly-spaced dots? Quadrilaterals from nrich.maths.org.

Sorting Logic Blocks
Use an on-screen interactivity to practise describing and sorting 2-D shapes.
Could you make some more shapes to add to the set? What would you make and why? Sorting Logic Blocks from nrich.maths.org.

Day 1 Teaching
Support children in drawing a co-ordinate using ‘across’, and ‘walk before you fly’. Draw all but the last point of some recognisable polygons and ask children to draw in the last point and record its co-ordinates. Draw a pentagon straddling both quadrants. Children sketch the shape, then label the co-ordinates.
Group Activities
Use the ‘Cycling co-ordinates’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
-- Plot co-ordinates and draw polygons in two quadrants.

Day 2 Teaching
Join points (-3, 1), (4, 1), (-1, 5) and (6, 5) for a parallelogram.
Children write the co-ordinates of each point. This parallelogram moves two squares to the right. What are the co-ordinates of its new position? Draw the new position and discuss how each x- value has been increased by 2, but the y-values have stayed the same. Repeat with other polygons.
Group Activities
-- Translate polygons on a grid; identify how co-ordinates change.

Day 3 Teaching
Draw a right-angled triangle in the right quadrant. Children pretend there is a mirror on the y-axis. We will reflect this triangle in the y-axis. Draw the reflected triangle in the left quadrant. Check each point is the same distance away from the y-axis as it was originally, and that it looks to be the same shape. Children label the co-ordinates.
Group Activities
-- Reflecting shapes and points in positive y-axis and predicting new co-ordinates
-- Extend to four quadrants

• Whiteboards & pens
• ‘Two quadrants’ image (see resources)
• Squared paper or maths exercise books
• Rulers
• ‘Two quadrants – blank’ sheets (see resources)
• ‘Translations’ sheet (see resources)
• Mirrors

Suggested for Day 1
Revise finding lines of symmetry (simmering skills)

Suggested for Day 2
Pairs to 200 (simmering skills)

Suggested for Day 3
Reading scales (simmering skills)

Day 1
Plot points to make polygons.

Day 2
Translate shapes, make translation patterns.

Day 3
Make patterns using reflections.

• What shape will you get if you join these points on a co-ordinate grid?
  (0, 3) (2, 5) (6, 5) (6, 1) (2, 1)
• A square has vertices at (0, 2) and (0, 6). What are the co-ordinates of its two other vertices?
• A triangle is moved 3 spaces to the right on the co-ordinate grid. Its new co-ordinates are: (2, 5), (–1, 2) and (5, 2).
  What were its original co-ordinates?
• Draw a rhombus and then reflect it in the y-axis.

In-depth investigation: Cycling Co-ordinates
Children use a sequence of co-ordinates to create quadrilaterals, investigating a conjecture around predicting shape types.
