Lesson 2: How many do you see?

Learning intentions

Success criteria

Students are learning that:

  • mathematicians work with others to solve problems
  • combinations of 2 numbers (between 0 and 10) when added together, form 10
  • the commutative property helps to recall addition facts
  • the symbol + means ‘add’ and the symbol = means ‘is equal to’
  • addition problems can be solved using advanced count-by-one strategies.

Students can:

  • give reasons about how many vegetables they counted
  • make groups of two numbers that add up to 10
  • recognise and use the + and = sign
  • recognise that 6 + 4 is the same as 4 + 6
  • convince other students of their thinking about how many
  • ask questions of others to understand their thinking.

Lesson 3: Exploring Shapes

Learning intentions

Success criteria

.All students are learning that:

  • shapes can be described by their attributes
  • shapes can be combined to make new shapes
  • mathematicians work within rules to solve problems.

All students can:

  • describe shapes by their attributes using appropriate language
  • manipulate and turn shapes to find solutions
  • solve problems within a set of rules.

In addition, students working towards Early Stage 1 outcomes can:

  • identify triangles, circles, squares, and rectangles
  • describe the attributes of a shape no matter what the orientation.

In addition, students working towards Stage 1 outcomes can:

  • identify shapes according to number of sides and vertices
  • accurately label shapes with correct vocabulary
  • combine 4 triangles to create new shapes.

Definitions ��Go through the definitions- record on board and discuss as whole class

  • Attributes are the traits or the properties of a shape or an object. Attributes help define the characteristics of the shape both visually, for example, its colour, and mathematically, for example, the length of the sides.
  • A polygon is a flat two-dimensional shape with 3 or more straight sides that are fully closed. The sides must be straight, not curved.
  • A vertex is where 2 straight sides of a two-dimensional shape meet. A side is the line segment joining two vertices of a two-dimensional shape.

Shape talk�Find resources of items of different shapesWhat do you notice about this shape?�How could you describe this shape by the number or length or sides?�How could you describe this shape by it's vertices?�How is this shape similar to that shape?�

Shape movement activity 

  • Play music on a device as students move around the space. When the music stops, call out an attribute. Students stand on the shape that fits the description. Some suggestions are:
  • Find a shape that has 4 sides. Eg a chair /door
  • Find a shape that has 3 vertices.
  • Find a shape that has all 4 sides the same length.
  • Once all students have found the correct shape, ask if they can name the shape and describe one other attribute that is unique to that shape.
  • Continue the game until all attributes and shapes have been named.

Polygon Hunt

  • How did you sort your polygons? Explain your reasoning.
  • Do some polygons fit in more than one sort? Why/why not?
  • Can you identify any other features of your shapes?
  • Can you think of another way to sort your polygons?
  • How did you record your thinking?

Lesson 4: Attribute Shape Patterns

Learning intentions

Success criteria

Students are learning that:

  • shapes can be different but share attributes
  • some attributes are mathematical and some are not
  • the same shapes can be sorted in different ways
  • information (data) can be presented in different ways.

Students can:

  • name and describe shapes
  • identify attributes across shapes
  • sort shapes based on more than one attribute
  • re-sort shapes based on a different attribute
  • create a table showing how they sorted shapes.

17 of 29

Attribute of shapes

  • What attributes are shared?
  • Is it possible to organise your collection into another two-way sort using different attributes?
  • How can we represent this information visually using pictures and symbols?

Lesson 5: Numbers have attributes too

Learning intentions

Success criteria

Students are learning that:

  • some attributes are mathematical, and some are not
  • numbers have attributes which can be used to describe and sort them
  • numbers can be different but share attributes
  • the same numbers can be sorted or categorised in different ways.

Students can:

  • recognise that numbers have mathematical attributes
  • describe numbers by their parts and their relationship with other numbers. For example, 10 is used in the numbers 10 to 19
  • organise numeral cards in a way that shows their shared attributes
  • explain why numbers can be sorted (or categorised) into more than one category.

Lesson 6: organising and counting a collection

Learning intentions

Success criteria

Students are learning that:

  • a large collection of objects can be organised into groups to support the count
  • organising objects into groups of 10 is an efficient way to count larger quantities
  • groups of objects can be used to form a visual representation of an amount.

Students can:

  • organise objects into smaller groups to see how many objects there are
  • use groups of 10 to organise and count large amounts
  • groups of objects can display an amount.

Ten frame filler

You will need:

A 0-9 sided die, 0-9 spinner or cards with 0-9 printed on them.

2 different coloured markers

a gameboard

How to play

Roll the dice.

Record the total rolled using one of the ten-frames in a single, sweeping movement.

If there is not enough space in any of the ten-frames, miss a turn.

Take it in turns filling in ten-frames.

A player who completes the ten-frame (for example, rolling a three and there is a ten-frame with 7 already filled), claims it by writing their initials on top of the ten-frame.

The player with the most ten-frames at the end is the winner!

Discuss/reflect

Was there a strategy that helped you to win the game?

What numbers do you think were the best to roll? Why?

Have we found all the combinations to 10?

What might happen if we had a third player? Would it make it easier or harder to win?

Lesson 7: How many dots?

Learning intention

Success criteria

Students are learning that combinations of numbers (number bonds) help quantify collections.

Students can:

  • recognise combinations of numbers to 10
  • group the dice collections to make groups of 10
  • describe why counting in tens and ones is efficient.

Lesson 8: Boxes of pencils

Learning intentions

Success criteria

Students are learning that:

  • the same collection of objects can be represented in different ways
  • mathematicians communicate their thinking using words, symbols, pictures, and numbers.

Students can:

  • use the structure of a box of 10 pencils to organise a large collection of objects
  • describe why counting in tens and ones is a good strategy
  • communicate their thinking about counting strategies.
