📚 WALT: Create, continue and describe two-variable patterns

We Are Learning To: link the step number to the number of objects and explain the rule.

Success criteria: I can continue a pattern, complete a table, describe the increase or decrease, and use my rule to find a later term.

Use cubes or tiles if you need them. Look for what happens next.

Step 1: ■    Step 2: ■ ■ ■    Step 3: ■ ■ ■ ■ ■

Step 4:

Number of squares: ______    The pattern increases by ______ each step.

■ ■   →   ■ ■ ■ ■   →   ■ ■ ■ ■ ■ ■   →   ______   →   ______

The rule is: start at ______ and __________________________ each step.

18   →   15   →   12   →   ______   →   ______

The rule is to __________________ each time.

✏️ Part 2: Link the two variables

Complete each two-variable record. The headings are colour-coded: 🔵 step number and 🟢 number of objects.

🔵 Step:    1    2    3    4    5

🟢 Objects:   1    3    5    ______    ______

Arrows: 1   →   3   →   5   →   ______   →   ______

🔵 Step:    1    2    3    4

🟢 Objects:   16    ______    ______    ______

Rule: The number of objects __________________________________________.

Step 1 has 2 objects, step 2 has 5 objects, and step 3 has 8 objects.

My rule is: __________________________________________________________

Step 10 has ______ objects.

🎨 Part 3: Design a pattern for a classmate

Support: You may use cubes, tiles, numbers or drawings. Keep your values mainly within 20.

Extension: Make the increase change each time, such as adding 1, then 2, then 3. Ask your classmate to find a later term.

🔵 Step:    1    2    3    4    Later step: ______

🟢 Objects:   ______    ______    ______    ______    ______

My rule: _____________________________________________________________

──────────── fold line ────────────

The later term is ______ because _____________________________________
