These scaffolds help students who are not yet ready for abstract thinking:
Place value mats with colour-coded labels: Hundreds = blue, Tens = green, Ones = red (matching base-10 block colours)
Reduced number range early in lesson (up to 500 instead of 999)
Colour-coded number cards to highlight digit positions
Strategic pairing with peer mentors who can verbally model reasoning
Continued use of base-10 blocks through comparison activity (not rushed to abstract)
Key Principle: Allow extra time in concrete stage. Some students need weeks with manipulatives
before transitioning to pictorial. Don't force premature abstraction.
🚀 Extension for Advanced Learners
If you finish activities early and want more challenge:
Work with 4-digit numbers (1,000-2,000) including harder renaming problems ("How many tens are in 1,350?")
Explore regrouping: "What must we do if we have 10 ones? What if we have 10 tens?"
Design your own "Fair Challenge" scenario with self-chosen numbers
Note: Challenge with depth (e.g., "explain three different ways to show 456"),
not just more of the same. Advanced learners benefit from open-ended problems.
♿ Accessibility Accommodations
This lesson is designed to be accessible to all learners:
Visual Supports
Captioned videos for pre-class material
Large-print worksheets and high-contrast place value charts
Colour-coded materials with distinct, high-contrast colours
Kinesthetic & Motor Supports
Extra time with physical base-10 blocks for kinesthetic learners
Magnetic/digital base-10 representations on interactive whiteboard for fine motor difficulties
Chunky markers and grips for students with limited dexterity
Multisensory Instruction
Verbal + visual instructions together
Repeat key vocabulary with accompanying gestures (flatten hands for "hundreds", make sticks with fingers for "tens")
Audio descriptions of visual materials
Universal Design Principle: Design activities so all students can participate meaningfully,
regardless of ability. Multiple means of representation, engagement, and expression built into every activity.
