My Word Book: Mathematics: Linking Literacy and Numeracy

This book focusses on mathematical vocabulary and provides teachers with lists of words (linked to the Australian Curriculum: Mathematics) that are appropriate for particular strands across F-6.

Activities

Adding auxilliary lines

This activity has a set of graded problems which require the addition of auxiliary lines in order for them to be solved.

Circle geometry investigations

In this series of activities, students investigate a particular situation in a circle to form a hypothesis. They then further explore using dynamic geometry software.

Complete the congruence proof

This cloze activity provides frameworks of varying support for developing congruence proofs.

Dissected proof

In this activity, students reconstruct a proof of Pythagoras' theorem based on similarity. Students arrange a set of cards, each with either one line of the proof or a reason, in the correct order.

Dynamic circle geometry

In this activity, pre-prepared learning objects allow all students to benefit from exploring dynamic circle geometry.

Geometry toolkit

When students write deductive proofs in geometry they need to draw on a significant store of knowledge and skills which they have acquired over a number of years.

Great angle chase

After they have been introduced to the circle geometry theorems, this activity gives students practice in recognising the relationships in more complex diagrams.

Hexagonal tangrams

In this activity, students use a tangram to explore a wide variety of hexagons.

Linking angles

This activity uses dynamic diagrams to explore a broad range of angle relationships in a variety of orientations.

Paper, pencil and protractor

In this activity, students construct all possible triangles which have three given measurements. They determine the conditions under which congruence can be guaranteed.

Pattern block hexagons

This is a practical activity using patterns blocks which encourages students to think more inclusively about hexagons.

Property match-up

This is a classroom activity in which students are required to match quadrilateral properties expressed in words with the corresponding properties indicated on a diagram.

Quadrilateral flowchart puzzle

This is a challenging classroom activity in which students are required to represent the hierarchy of the special quadrilaterals in a flowchart diagram.

Quadrilateral property quiz

In this classroom activity, students are given physical examples of quadrilaterals that they can fold and measure. They then manipulate digital versions of the same quadrilaterals.

Translating geometric descriptions

In this construction activity, students draw diagrams to illustrate geometric relationships.

Virtual congruence

In this activity, students manipulate virtual diagrams and confirm the congruence tests. Once the triangles are constructed, they can be transformed and superimposed on each other.
