Do rectangles with larger areas also have longer perimeters? Explore the relationship between the area and perimeter as the length and width are altered. Follow an investigation path using the HOTsheet. ### Drawing a floor plan

How do we know what a house will look like before it is built? Discover how house plans work by looking at the design of a house that Hugo's family is going to build. See how a floor plan shows the room layout. See drawings of what the house will look like from different views. ### Numeracy wrap: Round the outside

In this resource students will calculate the perimeter of different shapes, choose the appropriate measuring device, make different shapes from given perimeters ### Perimeter and area

This is a six-page HTML resource about solving problems with perimeter and area. It contains one video and nine questions, five of which are interactive. The resource discusses and explains solving problems with area and perimeter to reinforce students' understanding. ### Lengths and areas

This is a website designed for teachers and students in year 5, and addresses components of the length and area topic. It is particularly relevant for selecting appropriate metric units of measurement for length, perimeter and area, and calculation of the area of rectangles. There are pages for both teachers and students. ... ### Area

This is a colourful animation, with audio commentary, about finding the area of shapes. The resource defines what area is and presents examples of finding the area of a number of different shapes. The examples use different approaches to measuring, including 'larger than or smaller than', measuring with uniform blocks, ... ### Perimeters

This is a colourful animation, with audio commentary, that defines perimeter and describes how it can be calculated. The term 'perimeter' is linked to the boundary of a shape and, using the example of riding a bicycle around a large square, the process of calculating the perimeter is demonstrated. Each screen contains an ... ### Area of a square and a triangle

Do you know the formula for working out the area of a square? How about a triangle? Watch this short maths video to learn the formulas for both. ### Working out the areas

Do you know how to work out the area of a square, a rectangle or a triangle? Learn the simple maths formulas needed from this video. What would be the area of a rectangle with a height of 5cm and a length of 3cm? ### The divider: without remainders

Solve whole number division problems such as 156/6. Use a partitioning tool to help solve randomly generated division problems. Learn strategies to do complex arithmetic in your head. Split a division problem into parts that are easy to work with. This learning object is one in a series of four objects. ### Mixed-Up Maths

Join our host, Ed, as he finds himself in all types of situations where only his knowledge of Maths can help him. From saving the planet from Aliens, to creating a superhero that can stop a strawberry milkshake tidal wave. From searching for buried treasure, to jumping like a daredevil, or planning the greatest circus party ... ### Farm animals - unit 4

This is a teacher resource that contains a program outline, student activities, and links to images and videos relevant to teaching primary students about farm animals that are raised for food and fibre, with a particular focus on livestock needs and farming technologies. The program outline and supporting documents can ... ### Monumental measurement mess ups

Did you know that in Australia we use a metric system for measurement? See if you know the units of measurement for length, mass and volume. Find out what system the United States uses. You guessed it - they don't use the metric system! See how a mix up of these units can cause all kinds of mess ups. ### Numeracy wrap: The long and the short

In this resource students measure objects of different length in centimetres and millimetres, order lengths from shortest to longest, convert between millimetres, centimetres, metres and kilometres. ### Visualising two-dimensional and three-dimensional shapes

This collection comprises 24 digital curriculum resources, including learning objects from the series 'Shape sorter', 'Face painter', 'Geoboard', 'Photo hunt', 'Viewfinder' and 'Shape maker'. There are three categories: exploring two-dimensional shapes; visualising three-dimensional shapes; and making three-dimensional ... ### Enlargement transformations

This is a website designed for teachers and students in year 5, and addresses components of the enlargement transformations topic in geometry. It is particularly relevant for the concept of enlarging two-dimensional shapes and also contains material on enlarging drawings using grid paper. There are pages for both teachers ... ### Starting Smart: how are measurement units used?

This curriculum resource package is a ten-week primary years teaching plan and set of supporting resources to progress students' understanding of measuring using informal units to make accurate measurements expressed as formal units. Students estimate and measure a variety of attributes including length, area, volume, mass ... ### Geoboard

This iPad app is a tool to create line segments, vertices and polygons using coloured bands on a pegboard. There are two board sizes - a standard 25-peg board and a 150-peg board that allows a greater number and diversity of configurations. The bands come in eight colours and the shapes created can be filled with a transparent ... ### Pattern shapes, by the Math Learning Centre - iTunes app
