Mathematics, 4–6 years — 20 topics · MyLeoNes™ Kuks
20 mathematics topics written for 4–6 years — not a older text simplified. In teaching order, each a deck of five cards: the idea, why it exists, a worked example, the common trap and where you meet it.
Mathematics · 4–6 years
Before, after, and how long
Put events in order and notice the passing of time in daily life.
Comparing weight
We can compare how heavy things are, even when they look different.
Counting each object once
Counting is not only saying number words. It is matching one number word to each object, so the last number tells how many there are.
How much a container holds
Compare and explore how much different containers can hold.
Making numbers in different ways
A number can be made from smaller parts in more than one way.
Measuring length
Compare how long things are, then measure a length by repeating the same-sized unit.
More, fewer, or the same
Two groups can be compared by matching their objects. A group has more when some objects are left without a partner; it has fewer when it runs out first.
Number order
Learn that number words have a fixed order, and use that order to find what comes before and after.
Number symbols
Learn how written marks stand for amounts we can count.
Putting groups together
Addition describes what happens when a group gets joined by another group. We can find the new total by counting all the objects or by starting with the larger group and counting on.
Recognising flat shapes
A shape is a way a flat object is made. We can notice its sides and corners, and recognise the same shape even when it is turned, coloured differently, or made larger.
Repeating patterns
Notice a small order that repeats, and use it to predict what comes next.
Seeing small amounts
A small group can sometimes be recognised at a glance, without counting each object. This helps a child notice how many there are and check a count quickly.
Sharing equally
Equal sharing means giving the same number to each person or group. It is a first way to think about fairness, groups and division without needing a written calculation.
Solid shapes
Some shapes are objects you can hold, roll, stack, or slide.
Sorting objects
Objects can be put into groups when they share something, such as colour, shape or use. Sorting helps us notice what is alike and what is different.
Taking away
See subtraction as what remains when some objects leave a group.
Where things are
Words such as above, under, beside, inside and between tell where one thing is compared with another. A position depends on the objects and the viewpoint, not just on a picture.
Whole and half
A whole can be split into two equal parts called halves.
Zero means none
Understand that having none is still a number we can name and use.
