🗺️
Planning and Checking Multi-Step Problems
A good plan turns a tangled problem into simple steps — and a good check catches mistakes before they cost you. Learn to map out the steps, solve them, and prove your answer makes sense.
🔄
Drawing Life Cycle Diagrams
Learn to read and draw life cycle diagrams, using arrows and circles to show how living things grow and repeat.
🕸️
Ocean Food Webs
One ocean animal usually eats many foods, and is eaten by many others. See how dozens of food chains link together into a tangled ocean food web.
🐙
Ocean Animals and Their Adaptations
From streamlined sharks to glowing anglerfish, discover the clever body features and tricks that help ocean animals swim, breathe, hide, and hunt in the sea.
🎣
Deep-Sea Creatures
In the cold, crushing, pitch-black deep sea live some of the strangest animals on Earth. Meet glowing anglerfish, giant squid, and creatures that thrive with no sunlight at all.
✏️
Showing How You Got Your Answer
An answer is even better when you can show HOW you got it! Learn to draw circles, make marks, and lay out counters so everyone can see your thinking.
⬡
Regular and Irregular Polygons
Name polygons by their sides and tell regular shapes (equal sides and angles) from irregular ones.
⭕
Parts of a Circle
Name the centre, radius, diameter and circumference, and use diameter = 2 × radius.
📐
Measuring and Drawing Angles
Use a protractor to measure and draw angles, and name acute, right and obtuse angles.
📐
Finding Missing Angles
Use angle rules — straight lines, points, triangles and quadrilaterals — to work out missing angles.
🔎
Finding Missing Angles and Sides
Use angle rules and equal-side rules to work out missing angles and side lengths in shapes.
🔎
Reading Geometry Diagrams
Crack the code of geometry diagrams — right-angle squares, equal-side ticks, parallel arrows, and labelled corners.
📐
Classifying Angles and Shapes
Sort angles into right, acute, and obtuse, and name 2D shapes by counting their sides.
📐
Angle Rules
Learn the big angle rules — angles on a straight line add to 180°, angles around a point add to 360° — and use them to find missing angles.
🔺
What Makes a Triangle a Triangle
Every triangle follows one simple rule — 3 straight sides and 3 corners. Learn the rule and spot triangles everywhere!
📐
Understanding Angles
An angle is how much a corner opens. Meet right angles, sharp acute angles, and wide obtuse angles — and spot them everywhere!
🛤️
Parallel and Perpendicular Lines
Parallel lines run side by side and never meet, like train tracks. Perpendicular lines cross at a perfect right angle. Learn to spot both!
🕸️
Food Chains and Food Webs
Follow the flow of energy from the Sun through producers, consumers, and decomposers, and see how food chains link into tangled food webs.
▦
Area with Fractions
Find the area of rectangles with fractional sides by multiplying fractions straight across.
🥧
Pie Charts and Line Graphs
Construct pie charts by calculating sector angles, build line graphs from data, and read both to spot trends and solve problems.
⭕
Halves and Quarters of Shapes
Cut circles and rectangles into two and four equal shares, and use the words halves, fourths, and quarters like a pro.
📐
Using Simple Formulas
Plug numbers into formulas like P = 2(l + w) to find perimeters, areas, and more. Once you can substitute values, one formula works for every rectangle or triangle.
🔗
Generating Sequences
Build sequences from rules like 'add 3 each time' or formulas like 3n − 2, and tell whether a sequence is arithmetic, geometric, or neither.
🧮
Counting Objects to 20
Count collections of up to 20 things — in lines, circles, or scattered piles — and show numbers with counters, fingers, tally marks, and dots.
🖍️
Let's Draw!
Grab a pencil and discover the big secret of drawing: everything you see is made of circles, squares, and triangles — and you already know how to draw those!
📐
Shapes & Geometry
Discover the shapes hiding all around you, from pizza slices to soccer balls!
