Continue and repair repeated groups, then use patterns in a toy neighborhood.

Today we find the whole repeating group, preserve its order and repair a missing place.
| Term | What it means |
|---|---|
| Unit | The smallest group that repeats. |
| Repair | Restore a missing or misplaced part. |
A repeating pattern copies a group in the same order. Circle, square, square repeats three places even though it uses only two shape kinds. Call this smallest repeating group the unit. To continue, find your place inside the unit. To repair a missing card, compare it with the same place in a complete unit.

The bars separate complete units, not individual shapes.
Patterns keep order. Sorting groups matching kinds. Split five into one and four, or two and three; rejoin.
Build a neighborhood with 6–10 counted objects, a repeated border and two positional directions. Explain counts and the unit; revise when a guest arrives or a pattern piece changes. The adult records name, date, support and observations. Score counting, pattern, directions and revision: 0 not yet, 1 with mathematical help, 2 independently. Require 2 in each area; give feedback and a fresh retry otherwise. Reading prompts or gestures are allowed. Screen scores cannot verify performance.
Read the complete group.
▲ ● ■.
Three different kinds repeat in order.
Continue after ▲ ●.
Next is ■.
The third place is still needed.
Compare ▲ ● ● with ▲ __ ●.
Middle places match.
Both copies use the same order.
Restore the missing place.
Continue this repeating border: ▲ ● ● | ▲ ● ● | ▲ __. What comes next?

A toy path repeats dot cards: [● ●] [●] [●] [● ●] [●] [●]. Record the dot count on each card in the smallest repeating group, then the count on the next card.
| Dots on that card | |
|---|---|
| Unit: first card | |
| Unit: second card | |
| Unit: third card | |
| Next card |

Repair a toy border: [● ● ●] [●] [●] [● ● ●] [missing] [●]. Then split FOUR counters two ways: one left and the rest right; two left and the rest right. Complete each record.
| Number | |
|---|---|
| Dots on missing card | |
| Right part when left has 1 | |
| Right part when left has 2 |
