The National Council for Teachers of Mathematics (NCTM) in the US has produced a plethora of interactive resources to improve the teaching and learning of maths for everyone. The ITPS (interactive teaching programs) are available for both KS1 and KS2 maths and can be used by teachers and pupils alike.

### Coin Box

Learn how to count, collect, exchange, and make change for coins by manipulating coins using an array representation. KS1 KS2

### Deep Sea Duel

This strategy game requires you to select cards with a specified sum before your opponent (also available on iOS and Android).KS2

### Dynamic Paper

Need a pentagonal pyramid that's six inches tall? Or a number line that goes from ‑18 to 32 by 5's? You can create all those things and more! Place the images you want, then export it as a PDF or as a JPG image. KS1 KS2

### Equivalent Fractions

This applet allows you to create equivalent fractions by dividing and shading squares or circles, and match each fraction to its location on the number line. KS2

### Factorise

Dividing Numbers into Two Factors and Building Arrays to Represent Each Factorization KS2

### Fractal Tool

This applet allows you to explore iteration and patterns in shapes and numbers with fractals. KS2

### Fraction Models

Explore different representations for fractions including improper fractions, mixed numbers, decimals, and percentages. Additionally, there are length, area, region, and set models.
KS2

### Geometric Solids

This tool allows you to manipulate various geometric solids and investigate their properties.
KS1 KS2

### Pan Balance – Expressions

Using this interactive tool, you can practice arithmetic and algebraic skills, and investigate the important concept of equivalence. KS2

### Pan Balance – Numbers

Use this tool to strengthen understanding and computation of numerical expressions and equality using a balance scale.
KS2

### Pan Balance – Shapes

Use this tool to build up to algebraic thinking by exploring how to balance shapes of unknown weight.
KS2
