Chapters

1. 1Patterns in MathematicsLesson: Patterns in Mathematics · 15 sections · chapter quiz

   Mathematics is often called the study of patterns. Stacked oranges, tiles on a floor and the petals of a flower all hide number patterns that we can describe, predict and explain.

   • • I can describe and continue number sequences such as odd numbers, triangular numbers and square numbers.
   • • I can explain a pattern using a rule and a picture.
   • • I can connect number sequences with shape patterns.
2. 2Lines and AnglesLesson: Lines and Angles · 15 sections · chapter quiz

   The corner of a page, the hands of a clock and the opening of scissors all make angles. Geometry begins with simple ideas: points, lines and the turning between them.

   • • I can name and draw points, line segments, lines and rays.
   • • I can identify an angle, its vertex and arms, and measure it with a protractor.
   • • I can classify angles as acute, right, obtuse, straight and reflex.
3. 3Number PlayLesson: Number Play · 15 sections · chapter quiz

   Numbers can be played with like a puzzle. Some read the same forwards and backwards, some reveal surprising results when reversed and added, and estimation helps us check whether an answer makes sense.

   • • I can read, compare and use large numbers and their place values.
   • • I can find patterns in digits, such as palindromes and digit sums.
   • • I can estimate and reason about numbers using rules and puzzles.
4. 4Data Handling and PresentationLesson: Data Handling and Presentation · 15 sections · chapter quiz

   A class wants to choose a favourite fruit for a school picnic. Collecting the votes and presenting them clearly helps everyone see the result and decide fairly.

   • • I can collect and organise data in tally tables.
   • • I can read and draw pictographs and bar graphs with a suitable scale.
   • • I can interpret graphs and identify misleading presentations.
5. 5Prime Time: Factors, Multiples and PrimesLesson: Prime Time: Factors, Multiples and Primes · 15 sections · chapter quiz

   Two friends clap in a game: one claps every 3 counts, the other every 4. When do they clap together? Questions like this lead us into the world of factors, multiples and primes.

   • • I can find factors, multiples, common factors and common multiples.
   • • I can identify prime and composite numbers and co-primes.
   • • I can write a number as a product of primes (prime factorisation) and use divisibility rules.
6. 6Perimeter and AreaLesson: Perimeter and Area · 15 sections · chapter quiz

   Fencing a garden needs its perimeter; planting grass needs its area. The two ideas are different, and confusing them can cost money!

   • • I can find the perimeter of polygons, rectangles and squares.
   • • I can find the area of rectangles, squares and triangles using unit squares and formulas.
   • • I can explain that shapes with the same perimeter can have different areas.
7. 7FractionsLesson: Fractions · 15 sections · chapter quiz

   Three friends share 2 rotis equally. How much does each get? Fractions help us describe equal shares that are not whole numbers.

   • • I can represent fractions as equal shares and on a number line.
   • • I can find equivalent fractions and write fractions in lowest terms.
   • • I can compare, add and subtract fractions, including mixed fractions.
8. 8Playing with ConstructionsLesson: Playing with Constructions · 15 sections · chapter quiz

   Designers and engineers draw exact shapes. With only a ruler and a compass, we can draw circles, copy lengths and build accurate rectangles and squares.

   • • I can use a ruler and compass to draw circles and arcs of a given radius.
   • • I can construct squares and rectangles with given measures and check their properties.
   • • I can explain why a construction works using properties of shapes.
9. 9SymmetryLesson: Symmetry · 15 sections · chapter quiz

   Butterflies, rangoli, temple doors and many national flags look balanced. That balance is called symmetry, and mathematics helps us describe it precisely.

   • • I can identify lines of symmetry in shapes and pictures.
   • • I can complete a figure so that it is symmetric about a line.
   • • I can recognise rotational symmetry and find the angle and order of rotation.
10. 10The Other Side of Zero: IntegersLesson: The Other Side of Zero: Integers · 15 sections · chapter quiz

    A lift goes 3 floors below the ground for parking. A freezer is at 18 degrees below zero. To describe these, we need numbers on the other side of zero.

    • • I can describe negative numbers using real situations such as temperature, floors and money.
    • • I can place integers on a number line and compare them.
    • • I can add and subtract integers using a number line and tokens.
