This worksheet helps kids practice identifying AB patterns using simple geometric shapes.

Let’s look at each row one by one. We’re looking for an “AB pattern” — that means two shapes repeating over and over: A, B, A, B, A, B…

---

Row 1:
Shapes: □ △ □ △ □ ?

We see: Square, Triangle, Square, Triangle, Square...

So the next shape should be Triangle (because it goes ABABAB → next is B).

On the right side, we have to choose between a square and a triangle → pick the triangle.

---

Row 2:
Shapes: ○ ▭ ○ ▭ ○ ▭ ?

Circle, Rectangle, Circle, Rectangle, Circle, Rectangle...

This is already complete! But wait — the last shape shown is a rectangle, so if the pattern continues, the *next* one after that would be a circle.

But looking at the options on the right: circle or rectangle? Since the pattern ends with rectangle, and we’re being asked what comes *next*, it should be circle.

Wait — let me double-check the row:

It shows: ○ ▭ ○ ▭ ○ ▭ → that’s 6 shapes. The pattern is ABABAB. So if we’re to continue, the 7th shape would be A again → which is circle.

Yes → pick circle.

---

Row 3:
Shapes: □ ○ □ ○ □ ○ ?

Square, Circle, Square, Circle, Square, Circle...

Again, this is ABABAB. Next should be A → square.

Options on right: circle or square → pick square.

---

Row 4:
Shapes: ◣ ▭ ◣ ▭ ◣ ?

Right triangle pointing down-left, then rectangle, then same triangle, then rectangle, then triangle...

Pattern: Triangle, Rectangle, Triangle, Rectangle, Triangle → next should be rectangle.

Options on right: triangle or rectangle → pick rectangle.

---

✔ Final check:

Row 1: Ends with □ → next is △
Row 2: Ends with ▭ → next is ○
Row 3: Ends with ○ → next is □
Row 4: Ends with ◣ → next is ▭

All match the AB pattern.

Final Answer:
For each row, color the shape that continues the AB pattern:
- Row 1: Triangle
- Row 2: Circle
- Row 3: Square
- Row 4: Rectangle
