Daniel has six blocks. He takes one away. There are five blocks left. Five is one less than six.

Pick the number that is one less than four.

If we take away one brick from our four bricks, we’re left with one, two, three. This picture shows three bricks. One less than four is three.

Pick the number that is one less than eight.

The first row shows eight bricks. What is one less than eight? We can see that nine is more than eight. So, we know it’s not this row. Is seven one less than eight? Yes, it is. If we were to add one more brick to seven, we would have eight. So, we can say that eight is one less than seven. If we were to take away one of the eight bricks, there would be seven left.

One less than four is three. And one less than eight is seven. Finding one less than a number is the same as taking away one. Four take away one is three. And eight take away one is seven.
