Tap, listen and play with the numbers up to 1000: in tens, like the 1000 square of the ABN method used in many Spanish schools, or hundred by hundred to see every number from 0 to 999. And if you'd like it on paper, print it with or without gaps.
Tap any number: you'll hear its name and see its family and its neighbours
👉 Swipe the square sideways to see all the numbers
It's the big sister of the hundred square. It has the same 100 boxes, but each one is worth a ten: 10, 20, 30… up to 1000. Each row is a whole hundred (10 to 100, 110 to 200…), so your child sees that ten tens make a hundred and that going down a row is +100. With it they count in 10s and in 100s, place three-digit numbers and practise the jumps they'll use later in the grids.
It shows the numbers one by one, a hundred at a time: 0 to 99, 100 to 199… up to 999. It's the hundred square ten times over, so your child discovers that 347 "lives" in the same box as 47, but in the 300s. The +100 and −100 buttons move to another hundred and keep the path.
A number's family is its row on the square: in the tens view, the row from 310 to 400; in the hundred-by-hundred view, its ten (340 to 349). Its neighbours are the boxes just before and just after it: 330 and 350, or 346 and 348.
Tap a starting number and use the buttons: in the tens view, +10 and −10 move along the row and +100 and −100 jump to another row. In the hundred-by-hundred view there are +1 and −1 too. The path lights up as you go: it's the foundation of ABN calculation, moving in jumps of hundreds, tens and ones.
Roughly the first three years of Spanish primary school (ages 6 to 9): once your child is at home with the hundred square and starting on three-digit numbers. First exploring and hearing the names, then families and neighbours, and last of all the jumps and the Find it! game.
