Here are some links and resource to learn/update your maths skills.

Units of measure
 
Metric units of measure
In this module, you will study metric units of measure and how to convert from one unit to another.

Length or distance

Perimeter of squares, rectangles and triangles
In this module you will study how to find the perimeter (distance around) some of standard two-dimensional shapes such as squares and triangles.

Circumference of circles
In this module, you will learn about the number "pi" and you'll learn how to use pi to calculate the circumference (distance around) a circle.

Area 

Area of squares, rectangles and triangles
In this module, you learn how to find the area of some standard two-dimensional shapes.  

Area of circles
Here you will learn how to use pi to find the area of a circle.

Surface area of three-dimensional objects

Surface area of cubes, cuboids and triangular prisms
In this module, you will study how to find the surface area of various standard three-dimensional objects such as cubes and boxes. 

Surface area of cylinders
Here you can study how to find the surface area of a cylinder

Volume or capacity

Volume of cubes, cuboids and triangular prisms
This module discusses finding the volume (capacity) of various three-dimensional objects like cubes and boxes. 

Volume of cylinders, cones, spheres and pyramids
In this module, you will study how to find the volume of cylinders, cones, spheres and pyramids.

Basic Algebra

 Variables and expressions   
In this module you can learn what a variable is and how variables are used in algebra.

Order of operations  
In this module you can learn what order you must use when you simplify algebraic expressions.
 
Expanding expressions with brackets  
In this module you will learn how to remove the brackets from algebraic expressions.  
For example, you'll study how to change 3(x - 2) into 3x - 6.

 

In this module you can learn what exponents are and how to work with them.

 

Radicals basics  
In this module you can study how to work with square roots and cube roots.

 

In this module you can study how to substitute numbers into algebraic expressions.  
For example, you'll study how to find the value of (x + 2y) when x=3 and y=5.
 
In this module you can study how to substitute given values into a formula.  
For example, you'll learn how to find the perimeter of a square (the formula for this is p=2w + 2l) when you know the width is 10m and the length is 20m.

Similar triangles
In this module you will study similar triangles, which are triangles of the same shape but different size. 

The Pythagorean Theorem
In this module, you will study the Pythagorean Theorem, which describes the amazingly simple and useful relationship that exists between the sides of a right triangle.

Introduction to sine, cosine and tangent  
In this module, you learn how to find sines, cosines and tangents, and you'll also learn about a memory device called sohcahtoa.
