Our learning goal
I can understand and use important maths vocabulary.

What maths words do you know already?
Use this as a quick activation. Accept single words or short phrases such as add, minus, shape, equal, total, divide or angle.
Why maths words matter
Maths has special words.
These words help us:
read questions
explain ideas
solve problems
check answers
Keep language simple and concrete. Emphasise that understanding the words helps before any calculation starts.
Word and meaning
A maths word has a clear meaning.
When you know the word, you know what to do.
Example:
add means put numbers together
equal means the same value

Words can show actions
Some maths words tell us an action.
add
subtract
multiply
divide
You can gesture the actions or write one quick number example for each word aloud, but keep the slide vocabulary-focused.
Words can show size or amount
Some words describe numbers.
greater than = bigger
less than = smaller
equal to = the same
difference = how much is left between numbers
Make sure students do not confuse 'difference' with 'different'. In maths, difference links to subtraction or the gap between numbers.
Words help us read questions
In a question, key words give clues.
Example:
total often means add
left often means subtract
shared equally means divide
Say 'often' rather than 'always' so students do not overgeneralise keywords.
Which word means the same value?
difference
equal
greater than
subtract
Checks core meaning from the first vocabulary block. Distractors are real maths words from nearby slides.
Maths words and clues
In maths, words help us know what to do. add means put numbers together. equal means the same value. In questions, total often means add, and left often means subtract.
All blanks come from slides 3 to 6 and match the exact phrasing used there.
Addition words
These words often connect to addition:
add
plus
sum
total
altogether
in all

Subtraction words
These words often connect to subtraction:
subtract
minus
take away
difference
fewer
left

Multiplication and division words
These words often connect to:
Multiplication
multiply
times
product
Division
divide
shared equally
quotient
If 'quotient' feels advanced for the group, present it as a word they may see, not one they must use often.
Which word often means subtraction?
altogether
product
left
times
Tests keyword recognition across operation vocabulary.
Operation words
Some words show operations. sum and total connect to addition. Difference and fewer connect to subtraction. Product connects to multiplication, and shared equally connects to division.
Supports vocabulary sorting from slides 7 to 9. The abstract nouns are used because students have just seen them in lists.
Shape words
Maths also has shape words.
triangle has 3 sides
square has 4 equal sides
rectangle has 4 sides
angle is the space between 2 lines

Measurement words
We use words for measuring too.
length
width
height
area
perimeter
You may briefly remind students that perimeter is around a shape and area is inside a shape.
Number value words
Some words describe value and place.
digit = one number symbol
place value = a digit's value by position
even = in the 2 times table
odd = not in the 2 times table

Using the right word
Good maths talk is clear.
Say:
'The sum is 12.'
'8 is greater than 5.'
'The perimeter is 20 cm.'
The right word shows the right idea.
Model accurate sentence stems slowly for EAL learners. Students benefit from hearing full sentences, not only isolated terms.
What is the space between 2 lines?
area
angle
length
square
Checks understanding of shape and measurement vocabulary.
Shape and value words
A triangle has 3 sides. A square has 4 equal sides. The distance around a shape is perimeter. One number symbol is a digit, and a digit's value by position is called place value.
This consolidates slides 10 to 13 with key taught definitions and sentence patterns.
Write one maths sentence with a key word.
Encourage one short sentence using any correct maths word from the lesson, for example: 'The sum is 10.' '8 is greater than 6.' 'The perimeter is 12 cm.' Focus on clear use of vocabulary, not perfect grammar.
What is one new maths word you learned?
Reflection only. Invite brief answers such as 'sum and total' or 'difference'.
What helped you understand the words best?
Reflection only. Students may mention pictures, examples, sentence stems, or word lists.
