C1.1 Identify and describe repeating elements and operations in a variety of patterns, including patterns found in real-life contexts.
Activity 1: Discovering Patterns! (Recognize)
Directions
Ask students to identify patterns in and around the school. To do this, suggest that they look closely at the walls, floors, windows, landscaping, etc.
Help them to discover patterns by asking questions such as:
- Look at the walls (windows, bricks, etc.) of the school. Do you notice how the colours on the wall change? Do you notice how the bricks are arranged?
Is there a consistent order (or core) in the way the windows are arranged (bricks, tiles covering the floors, trees, etc.)?
Can you describe the pattern?
Next, ask them to represent, using concrete materials or a drawing, an observed pattern rule. The students must then create a pattern to show that there is indeed a consistent pattern rule.

Activity 2: Pattern Museum (Describe)
Directions
Create a "pattern museum" on a bulletin board with pictures or drawings of patterns discovered at home. Ask relevant thought-provoking questions such as:
- How would you describe the Pattern Museum to someone visiting our class?
- Do all these examples have patterns? How do you know?
- If you had to group some of these images together, which ones would you put together and why?
This questioning prompts students to discuss the types of patterns in the museum and the characteristics of a pattern.

Activity 3: From Which Country? (Description)
Fabrics have always been a way to express the cultural heritage of people. That is why the colours and patterns of fabrics often give a clue as to the nationality of the people.
Show students a piece of fabric. Ask them to describe the patterns in the fabric, focusing on patterns and colours, to show how the same pattern can look very different if one of the attributes is colour, and to compare the patterns in the fabric with those in their own clothes.
Exploring fabrics allows students to discover different cultural expressions and to realize that the mathematics they learn in school has a connection to the world around them.

Activity 4: Describe the Operation that is Repeated
Present the following situation to the students.
Each week, students at the school have physical education classes. Here is a chart that summarizes the number of physical education classes students had during 10 weeks.
| Number of Weeks | Number of Classes |
|---|---|
| 1 | 4 |
| 2 | 8 |
| 3 | 12 |
| 4 | 16 |
| 5 | 20 |
| 6 | 24 |
| 7 | 28 |
| 8 | 32 |
| 9 | 36 |
| 10 | 40 |
Ask students the following questions:
- What operation is being repeated in the "Number of Weeks" column?
- What operation is being repeated in the "Number of Classes" column?
