Subtraction

Subtraction

Use words, numbers and alternate terminology to build a strong grasp of subtraction - a multi-faceted approach.

SUBTRACTION is the skill of taking numbers from each other - If you start with five lollies and you eat two is five less two makes three; five minus two equals three; 5-2=3.

The language of SUBTRACTION is learnt - the words, the concepts, the representative figures.

MATHSMART gives you practice with the words, numbers, figures and symbols of the four operations.

Using Words
	Learn about the various words that can be substituted in place of either numbers or symbols. Use language such as 'less _ is' or 'minus _ equals' with words or numbers. Count down from a single number. Become familiar and comfortable with the manipulation of numbers written in a word format.

	Learn one of the most effective technique for solving subtraction equations. Subtract between two to four numbers, each ranging from one digit to three, from each other at once. Become familiar and comfortable with solving subtraction equations via the use of a vertical layout.

Renaming and Grouping
	Explore and recognise patterns and relationships between and within numbers. Break numbers into their component parts. Re-arrange units, tens, hundreds and thousands. Become familiar and comfortable with numbers.
