Interactive On-Line Mathematics Resources


The purpose of this website is to provide access to On-line Interactive Mathematics Activities. This is intended mainly for junior students. These activities are intended to support the teaching and learning of objectives found in the New Zealand Mathematics Curriculum.

In designing this website, it has been the intention to provide interactive activities for students to use. By interactive, it is meant that students are required to  provide responses as required by the given programmes. Students will frequently be provided with feedback.

The layout of this website is designed primarily to list suitable websites. For each website, notes are provided suggesting the approximate areas of the curriculum for which the activity is relevant. These notes may also suggest how the website can best be used, and in some cases  specific areas of the website that should be accessed.

This website has activities for four areas: Number and Operations, Algebra,
Geometry, Measurement, and Data Analysis and Probability.  Access activities
 for Grades 6-8 or Grades 9-10.  The next 23 sites listed provide access to
specific activities from within this website.

Solve simple linear equations using  balance beam scales.

Solve simple linear equations using  balance beam scales.  Negative values are
added using balloons.

Input given numbers into a function machine. Recognise the function and
complete the function for other values.

Tower of Hanoi.  The level of difficulty varies with the number of discs used.

A puzzle involving adding positive and negative integers.

A puzzle involving adding positive whole numbers.

Good activity to practice adding fractions with different denominators.

Good activity to practice forming equivalent fractions.

Puzzle involving adding whole numbers.  Solve puzzles by arranging numbers
on a diagram so that they add up to a given value.

Good practice in converting fractions to percentages.

Turtle Geometry.  Good for reinforcing concepts of Translation and Rotation.

Playing with reflections.  This illustrates what happens to the image when the
object or the mirror line changes position.

Playing with rotation.   This illustrates what happens to the image when the
object changes position or the angle of rotation is altered.

Playing with Translation.   This illustrates what happens to the image when the
object changes position or the distance or direction of the translation is altered.

An activity to prove Pythagoras's Theorem.

Tangrams Puzzles.

Fill and pour between two containers to obtain a set volume.  A good
application of Volumes.

How High.  This is a good application of the formulae for finding the volumes
of prisms, especially cuboids and cylinders.

Spinner Simulations.  This is a good activity in designing spinners, predicting
results, and observing the outcome.

Coin Tossing Simulation.  Click on Activities and investigate Heads In A Row,
Shooting Free Throws-1, and Manufacturing Process.

Practice in drawing Pie Charts.  It may be worth finding and identifying data
that students can graph first.

Drawing Histograms and Box and Whisker Graphs.  It may be worth collecting data which can be graphed before doing this activity (for example heights of boys and girls in the class).

Scatter Graphs.  Students measure their heights and hand-spans (or arm-spans) and then use this programme to draw a scatter graph.

Good activity for students to practice their multiplication tables.  Multiples of a
given number need to be identified.

Good practice for adding two whole numbers.  Students race against the clock
to add pairs of whole numbers.

Eight activities involving THE GOLDEN RATIO.  These include Everyday
Objects, Architecture, Art, and Nature.  Also two methods for Constructing
Golden Rectangles.

Adding Integers

Subtracting Integers

Dividing Integers

Simple Perimeter Problems (units are Imperial)

Area of Triangle Problems (units are Imperial)

Area of a Parallelogram Problems ( units are Imperial)

A good website to base 'A History of Pi' activity upon.

Interactive practice on basic maths skills.

Activities in Number, Algebra, Measurement, and Space suitable for less able
to average Year 9 and some Year10 students. Note: Use Level G

Students drag numbers onto  number lines. Box and Whisker Graphs are
automatically drawn from this data.  This illustrates well how Box and Whisker
Graphs can be used to compare averages and spread.

Demonstrates a method of establishing the value of Pi.

Create a spinner and observe what happens to the theoretical and experimental
 probabilities as the number of spins is increased.

Students place tickets in a box and then a random sample is  taken.  Students
can compare the theoretical and experimental probabilities as the sample size is varied

Simulation of a forest fire.  Good for developing Probability concepts.

Practice for times tables.


Practice at adding single digit whole numbers.

Bomb Number: Arcade game used to answer simple division questions and
develop multiplication skills.

Build a Bug: Speed Arithmetic practice on the four operations.

Arcade Game where students 'crunch' multiples of a given number.  Good for
practicing multiplication skills.

Mathematical Interactivities-Puzzles, Games, and other Online Resources.

400 websites chosen for their interactivity and grouped into 5 search categories.

Covers Number, Shape and Space, Measurement, and Handling Data. 
Consists of an online lesson,  followed by a simple multi-choice test.

Online lesson on Mean, Median, Mode, and Range, followed by a multi-choice

A lesson on Range, followed by a short interactive test.

A lesson on Mode, followed by a short interactive multi-choice test.

A puzzle the aim of which is to make pentaminoes fit onto a rectangular grid.

Students are able to alter and read the lengths of a right angled triangle and
thus establish Pythagorean Triples and  Pythagoras's Theorem.

Create a Bar, Pie, Area, XY, or Line Graph.  Students need data to graph.

Pythagoras of Samos.  A good website to base a History of Pythagoras
Assignment on.

Measuring angles with a Protractor and learning to interpret the labelling of

History of Pi. Ludolph's Tombstone.

The Pi Pages. Good for basing a History of Pi assignment on.  Go to
'continuing updates' for more information.

Web Sudoko

Covers Line and Rotational Symmetry.  Many applications given. A interesting

A Biography of Women Mathematicians.

A collection of lessons and worksheets designed to assist students in the study
of Algebra.

Building congruent figures using pentaminoes.

Stick or Switch.  A simulation of a TV game show where students explore the
best strategy that will lead to a prize.  A good application of Probability

Multiplication Table Applet. Good to help students understand multiplication
and learn multiplication facts.
