• I can use diagrams to compare and evaluate expressions
• I can decide whether expressions are equivalent for all values or only some

Have students write these in their math journals!]]> 2025-05-05 13:38:28 UTC https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466192 ksoto3_1 https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466197 6.EE.A.4: Identify when two expressions are equivalent
6.EE.B.5: Use substitution to determine if an equation is true for specific values

These foundational skills will support future algebraic reasoning! 🎯]]> 2025-05-05 13:38:28 UTC https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466197 ksoto3_1 https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466251 2025-05-05 13:38:30 UTC https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466251 ksoto3_1 https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466255 - Set A: 2x + 3 and 3 + 2x
- Set B: 3x and x + x + x
- Set C: 2x + 4 and 2(x + 2)

Students will use these for hands-on exploration of equivalence!]]> 2025-05-05 13:38:30 UTC https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466255 ksoto3_1 https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466275 Write on board: 'Is 3 + 4 the same as 4 + 3?'
Have students discuss with shoulder partners and justify their thinking. This activates prior knowledge about the commutative property!]]> 2025-05-05 13:38:31 UTC https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466275 ksoto3_1 https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466278 1. Draw tape diagram for 2x + 3
2. Draw tape diagram for 3 + 2x
3. Guide discussion: Why are these equivalent?
4. Introduce substitution method with x = 2

Use think-aloud strategy to model reasoning! 🤔]]> 2025-05-05 13:38:31 UTC https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466278 ksoto3_1 https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466283 1. Compare expressions using tape diagrams
2. Test equivalence by substituting values
3. Complete 'Equivalent or Not?' worksheet

Circulate to support and gather formative assessment data!]]> 2025-05-05 13:38:31 UTC https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466283 ksoto3_1 https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466285 Give students the expressions 4x and 2x + 2x
1. Are they equivalent?
2. Prove it two different ways

Collect tickets for assessment of understanding!]]> 2025-05-05 13:38:31 UTC https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466285 ksoto3_1 https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466295 • Provide pre-drawn tape diagrams for struggling students
• Offer expression cards with simpler numbers first
• Create anchor charts showing steps for substitution
• Allow use of calculators when needed]]> 2025-05-05 13:38:31 UTC https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466295 ksoto3_1 https://padlet.com/ksoto3_1/5ad2idto93h4o9xq/wish/3436466296 • Create their own equivalent expressions
• Write a story problem that uses equivalent expressions
