Show Answer Key & Explanations Step-by-step solution for: Complete the Patterns - Worksheet 1 | All Kids Network
Let’s go step by step to solve each pattern.

---

Pattern 1: Red Diamond, Orange Circle, Red Diamond, Orange Circle, Red Diamond, Orange Circle, ____, ____

Look at the sequence:
- Red Diamond
- Orange Circle
- Red Diamond
- Orange Circle
- Red Diamond
- Orange Circle

It’s repeating every two shapes: Red Diamond → Orange Circle

So after the last Orange Circle, the next should be:
→ Red Diamond (to start the pair again)
→ Orange Circle (to complete the pair)

So blanks are: Red Diamond, Orange Circle

Pattern 2: Purple Square, Yellow Triangle, Purple Square, Yellow Triangle, Purple Square, Yellow Triangle, ____, ____

Sequence:
- Purple Square
- Yellow Triangle
- Purple Square
- Yellow Triangle
- Purple Square
- Yellow Triangle

Repeating every two: Purple Square → Yellow Triangle

After last Yellow Triangle:
→ Purple Square
→ Yellow Triangle

Blanks: Purple Square, Yellow Triangle

Pattern 3: Blue Circle, Pink Square, Pink Square, Blue Circle, Blue Circle, Pink Square, ____, ____

Let’s write it with positions:

1. Blue Circle
2. Pink Square
3. Pink Square
4. Blue Circle
5. Blue Circle
6. Pink Square

Hmm… let’s look for a repeating unit.

From position 1–3: Blue Circle, Pink Square, Pink Square
Then 4–6: Blue Circle, Blue Circle, Pink Square — not same.

Wait — maybe group as pairs?

Positions 1–2: Blue Circle, Pink Square
Positions 3–4: Pink Square, Blue Circle ← different
Not that.

Try looking at groups of 3:

Group 1: Blue Circle, Pink Square, Pink Square
Group 2: Blue Circle, Blue Circle, Pink Square ← not matching

Wait — what if we look at symmetry or alternation?

Actually, let’s list them again:

1. Blue Circle
2. Pink Square
3. Pink Square
4. Blue Circle
5. Blue Circle
6. Pink Square

Notice:
- Positions 1, 4, 5 → Blue Circles? Not consistent.

Alternative idea: Maybe it’s based on counting?

Blue Circle appears at 1, 4, 5 → three times so far
Pink Square at 2, 3, 6 → also three times

But order matters.

Wait — perhaps it’s:
[Blue Circle, Pink Square, Pink Square] then [Blue Circle, Blue Circle, Pink Square] — but that doesn’t repeat.

Another approach: Look at transitions.

From 1→2: Blue → Pink
2→3: Pink → Pink
3→4: Pink → Blue
4→5: Blue → Blue
5→6: Blue → Pink

So the pattern of changes is:
Change, Same, Change, Same, Change...

That suggests next should be “Same” → so after Pink Square (position 6), next should be another Pink Square? But that breaks the alternation.

Wait — let’s try grouping differently.

What if the pattern is:
Blue Circle, Pink Square, Pink Square,
then Blue Circle, Blue Circle, Pink Square,
then... what comes next?

Maybe it’s building up? Like:

First group: one Blue, two Pinks
Second group: two Blues, one Pink
Third group: maybe three Blues? Or back to one Blue?

But we only have two blanks.

Alternatively, think of it as alternating blocks:

Block A: Blue Circle, Pink Square, Pink Square
Block B: Blue Circle, Blue Circle, Pink Square
Then Block C? What would come next?

If Block A has 1 Blue + 2 Pinks
Block B has 2 Blues + 1 Pink
Then Block C might have 3 Blues? But we only have two slots.

Wait — maybe it’s simpler.

Look at the entire sequence:

Blue Circle, Pink Square, Pink Square, Blue Circle, Blue Circle, Pink Square

Let me number them:

1: Blue Circle
2: Pink Square
3: Pink Square
4: Blue Circle
5: Blue Circle
6: Pink Square

Now, notice:

Positions 1, 4, 5 → Blue Circles
Positions 2, 3, 6 → Pink Squares

But positions 4 and 5 are consecutive Blues, while 1 is alone.

Perhaps the pattern is:
Start with one Blue, then two Pinks; then two Blues, then one Pink; then maybe three Blues? But we don’t have space.

Wait — what if we consider the pattern as:

[Blue Circle], [Pink Square, Pink Square], [Blue Circle, Blue Circle], [Pink Square], ...

That seems messy.

Alternative idea: Maybe it’s symmetric?

Let’s see:
1: Blue
2: Pink
3: Pink
4: Blue
5: Blue
6: Pink

If we mirror around center between 3 and 4:

Left: 1=Blue, 2=Pink, 3=Pink
Right: 4=Blue, 5=Blue, 6=Pink — not symmetric.

Wait — here’s a better way:

Look at the sequence as pairs:

Pair 1: (Blue Circle, Pink Square)
Pair 2: (Pink Square, Blue Circle)
Pair 3: (Blue Circle, Pink Square)
Pair 4: (Blue Circle, ???) — wait, we have six items, so three pairs.

Actually, let’s group into triplets:

Triplet 1: Blue Circle, Pink Square, Pink Square
Triplet 2: Blue Circle, Blue Circle, Pink Square

Now, compare:

Triplet 1: B, P, P
Triplet 2: B, B, P

So first element same (B), second changed from P to B, third same (P)

Then Triplet 3 might be: B, B, B? But we only have two blanks.

We need to fill positions 7 and 8.

After triplet 2 (positions 4,5,6: B,B,P), what comes next?

If the pattern of triplets is changing the middle element:

Triplet 1: B, P, P
Triplet 2: B, B, P
Triplet 3: B, B, B? Then position 7=B, 8=B? But that’s only one shape per blank? No, each blank is one shape.

Positions 7 and 8 are separate.

Perhaps the pattern is:

The number of consecutive same shapes increases?

From start:

- One Blue (pos1)
- Two Pinks (pos2-3)
- Two Blues (pos4-5)
- One Pink (pos6)
- Then maybe two Blues again? But pos7 and 8.

After pos6 (Pink), if we follow the "two Blues" pattern, but we had two Blues already at 4-5.

This is getting complicated.

Let me try a different approach.

List the shapes in order:

1. Blue Circle
2. Pink Square
3. Pink Square
4. Blue Circle
5. Blue Circle
6. Pink Square

Now, let's see the difference between consecutive:

1 to 2: change
2 to 3: same
3 to 4: change
4 to 5: same
5 to 6: change

So the pattern of "change" and "same" is: C, S, C, S, C

So next should be S (same as previous)

Previous is Pink Square (pos6), so pos7 should be Pink Square

Then pos8: after S, it should be C (change), so from Pink Square to Blue Circle

So pos7: Pink Square
pos8: Blue Circle

Let’s check if that makes sense.

Sequence would be:

1. Blue Circle
2. Pink Square
3. Pink Square
4. Blue Circle
5. Blue Circle
6. Pink Square
7. Pink Square
8. Blue Circle

Now, look at the "change/same" pattern:

1-2: C
2-3: S
3-4: C
4-5: S
5-6: C
6-7: S (Pink to Pink)
7-8: C (Pink to Blue)

Perfect! The pattern of transitions is alternating: Change, Same, Change, Same, Change, Same, Change...

So for positions 7 and 8: Pink Square, Blue Circle

Blanks: Pink Square, Blue Circle

Pattern 4: Green Triangle (pointing left), Green Triangle (pointing left), Blue Triangle (pointing left), Blue Triangle (pointing left), Green Triangle (pointing left), Green Triangle (pointing left), ____, ____

Wait, let's read carefully:

The shapes are:

1. Green Triangle (left-pointing)
2. Green Triangle (left-pointing)
3. Blue Triangle (left-pointing)
4. Blue Triangle (left-pointing)
5. Green Triangle (left-pointing)
6. Green Triangle (left-pointing)

So it's: GG, BB, GG, ...

So the pattern is: two Greens, two Blues, two Greens, ...

Next should be two Blues.

So pos7: Blue Triangle (left-pointing)
pos8: Blue Triangle (left-pointing)

Blanks: Blue Triangle, Blue Triangle

Pattern 5: Yellow Diamond, Red Rectangle, Yellow Diamond, Red Rectangle, Yellow Diamond, Red Rectangle, ____, ____

Simple: Yellow Diamond, Red Rectangle, repeating.

After last Red Rectangle (pos6), next is Yellow Diamond, then Red Rectangle.

Blanks: Yellow Diamond, Red Rectangle

---

Now, summarizing all answers:

Pattern 1: Red Diamond, Orange Circle
Pattern 2: Purple Square, Yellow Triangle
Pattern 3: Pink Square, Blue Circle
Pattern 4: Blue Triangle, Blue Triangle
Pattern 5: Yellow Diamond, Red Rectangle

Final Answer:
Red Diamond, Orange Circle, Purple Square, Yellow Triangle, Pink Square, Blue Circle, Blue Triangle, Blue Triangle, Yellow Diamond, Red Rectangle
