Numbers to 20
Counting, comparing, and the first adding and taking away — built on objects and a number line rather than on words a new reader cannot yet read.
Learn this now 💯Numbers to 100
Numbers up to 100 come apart into tens and ones, and go back together again. The same tens and ones then turn up on a clock face and in a handful of coins.
Learn this now ✖️Multiplication and Division
Multiplication starts as counting equal groups, and division is the same picture read from the other side. By the end the tables that matter come quickly, and a word problem no longer needs guessing.
Learn this now 🍰First Fractions and Decimals
A fraction is a piece of something, and a decimal is another way of writing the same piece. We start with a cake and a number line and finish with shekels and agorot.
Learn this now 🧮Bigger Multiplication and Division
The step from the times tables to numbers that no longer fit in your head. Multiplying and dividing on paper, with an estimate alongside every answer to check it is sensible.
Learn this now 🍕Fractions
A full pass through fractions, from what the denominator actually counts to adding and subtracting fractions whose denominators do not match.
