Browse by skill
By what your child does, rather than by grade.
Grade is the usual way in, and it is the front door of this site. But if you already know the sticking point — they cannot place a fraction, or they read 43 as bigger than 51 — this is the faster route. Activities appear under every skill they use, so most appear more than once.
Choosing an answer
Picking from a few options, with the wrong ones chosen to catch a specific misunderstanding.
Counting Crew
Count them, name the next number, and find who is 4th in line.
Shape Sorter
Name the shape, then count its sides.
Ten-Frame Flash
The dots flash up. How many did you see?
Adding to Twenty
Sums and differences to 20, starting with the easy ones.
Tens and Ones
How many tens? How many ones? Then add them up.
Clocks and Rulers
What time does the clock say? How many units long is it?
Halves and Quarters
Split the shape fairly. Is that a half or a quarter?
Make Ten Race
One number shows. Tap what it needs to make ten.

Arrays and Equal Groups
Count the rows, count the columns, find the total.
Close to a Hundred
Four digits, two numbers. Get as close to 100 as you can.
Fraction Number Line
Halves, thirds, fourths and eighths — find them on the line.
Round and Reckon

Time and Data
How long did it take? And what does the graph say when each square is worth five?
Fact Family Forge
Three numbers make four facts. Find the missing one.
Array Architect
How many squares? Then: does 4×6 match 6×4?

Which numbers divide it exactly? And which numbers have no pairs at all?
Decimal Drop
Where does 0.35 land? And what fraction is that?
Decimal Place
Tenths, hundredths, thousandths — line up the point.
The Standard Algorithm
The written methods, at full size. Two digits by two, and long division.

Long Multiplication
Break it into parts, multiply, put it back together.
Equivalent Fractions
Same amount, different name. 2/4 is 1/2.
Angles and Lines
Acute, right, obtuse — then work out the missing angle.
Factor Forest
Which numbers divide it exactly? And which numbers have no pairs at all?

Three times as many is not three more. Here is the difference.
Division Descent
Climb down: how many times does it go?
Fraction Foundry
Common denominators, then the four operations.
Decimal Place
Tenths, hundredths, thousandths — line up the point.
The Standard Algorithm
The written methods, at full size. Two digits by two, and long division.
Volume and Space
Length times width times height — how many cubes fit?
Placing numbers on a line
Estimating where a value sits between two landmarks. The most heavily evidenced representation in primary maths.
