Australian Curriculum: Description
Yr2 – Recognise and interpret common uses of halves, quarters and eighths of shapes and collections (ACMNA033); Yr3 – Model and represent unit fractions including 1/2, 1/4, 1/3, 1/5 and their multiples to a complete whole (ACMNA058)
Teaching ideas
Year 9s could even read this book and be asked to place all fractions mentioned on a number line from smallest to largest. Year 2/3 ideas - have students match the abstract (5/8) to a picture/scenario from the story. Explore and investigate other examples of fractions in the real-world.

Australian Curriculum: Description
Calculate perimeter and area of rectangles using familiar metric units (ACMMG109)
Teaching ideas
Pages at the back give teachers ideas and extension activities. E.g. How else could she have configured her dining room for the 32 guests? Cut and paste to assist students at the representational level of understanding. Create table arrangements for 12, 16, 24, 36 guests coming to the party.

Number and Algrbra – Number and Place Value – Develop efficient mental and written strategies and use appropriate digital technologies for multiplication and for division where there is no remainder (ACMNA076)
Teaching ideas
Students could investigate other numbers that divide equally. What if the original batch had been 24/36/48. How would that have been shared between the guests (2, 4, 6, 12)

Maths Concepts
Australian Curriculum: Description
Year 5 – Measurement and Geometry : Shape – Connect three-dimensional objects with their nets and other two-dimensional representations (ACMMG111); Year 6 – Measurement and Geometry : Shape – Construct simple prisms and pyramids (ACMMG140); Year 7 – Measurement and Geometry : Shape – Draw different views of prisms and solids formed from combinations of prisms (ACMMG161); Year 8 – Measurement and Geometry : Shape – Investigate the relationship between features of circles such as circumference, area, radius and diameter. Use formulas to solve problems involving circumference and area (ACMMG197).
Teaching ideas
* Year 5 students could use page 5 to "form the solids and find their places"; * Year 6 students could use page 5 to "form the solids and find their places"; * Year 7 students could investigate Euler's Law by folding nets to form prisms and pyramids. They =could then draw up an investigation table (page 12) and draw their own conclusions; * By year 8 the mathematical vocabulary students know should enable them to understand and apprecaite the entire book. The teacher could pose the problem from the book without reading it, and have students work in groups to solve it. Were the steps you took to solving it the same as Radius and Vertex's?

Australian Curriculum: Description
Number and Algebra : Number and Place Value – Solve problems involving division by a one digit number, including those that result in a remainder (ACMNA101); Investigate index notation and represent whole numbers as products of powers of prime numbers (ACMNA149)
Teaching ideas
* Have students mathematically represent the ideas in the book. i.e. concrete with actual bugs, representational with tally marks and abstract would be the mathematical numbers and symbols (25 ÷ 2 = 12 r1; 25 ÷ 3 = 8 r1; 25 ÷ 4 = 6 r1; 25 ÷ 5 = 5). Year 7s could use this as an introduction to prime numbers and non-prime numbers. What are the factors of 24 and 25.
