Connect shape parts

The option with a bump still on the right-hand edge is what you get by sliding the second piece across without turning it the right way round, so its bump ends up on the outside. Check that the sticking-out part and the bitten-out part face each other before you join anything. The wrong answers on this skill are built out of that, not out of random numbers, so it is worth naming out loud before your child meets it under time pressure.

Point at the next move rather than explaining the whole rule. Find the part that sticks out and the hole that is the same size and shape as it. Those two have to meet, and once they do the rest of the outline is just the two pieces side by side.

The skill map draws the line here: No stretching or overlap unless stated. A question past that line is testing a different named non-verbal reasoning skill, which is worth knowing before you spend a week practising the wrong one.

The spatial strand holds 8 skills that are tested together, and the pages next to connect shape parts are count cubes in a structure, find an embedded shape and match a solid and its view. Each has its own exercise and its own link, and none of them needs an account.

Use Shape Welder, embedded on this page. It is the exercise the skill map attaches to connect shape parts, it runs in the browser with no account to make, nothing is scored, and nothing a child does here is recorded or sent anywhere. It also has its own link, so you can send it to a child without sending them anywhere else first.
