🌱 The Pi Garden
The Greenhouse
Practise sums until you can do them without thinking, so your head is free for the interesting bits.
First, how many there really are
People say there are a hundred and forty-four times tables facts to learn, but once you take out the ones, the tens and the repeats, there are only 55. You already know a load of them. Let’s find out which, so the greenhouse stops asking you about those.
Nothing sorted yet.
It asks fifteen at a time, and you can stop whenever you like. It’ll remember where you got to.
Pick a bed
Today’s knot 🪢
Use the four numbers to make the target. You can use them in any order and add, take away, times or divide. Every knot can be done.
The whole table
Squares turn green as you learn the facts. Learn 7 × 8 and two squares go green, because 8 × 7 is the same fact.

This wipes everything you’ve done so far and goes back to an empty table.
