Provide learners with sets of 10–20 digit bricks and ask them to build quantities that match written digits from 0–20. Use clear grids or tens frames, and check accuracy by counting aloud together, touching each piece once to avoid skipped or double counts.
Include quick tasks where students compare two models, circling the larger total or matching equal sets. Aim for a mix of single-digit and teen values, as this highlights place value without adding complex steps.
Reinforce early addition by prompting children to combine two brick groups and record the total. Keep sums within 10 for beginners and extend to 20 for confident learners. Provide space for drawing the finished model so progress can be reviewed later.
Finish each page with short reflection prompts such as “How many more bricks do you need to reach 10?” This encourages mental calculation while keeping the activity visual and concrete.
Digit Brick Practice Pages
Set a clear quantity target between 0 and 20 and ask learners to build a matching model with colour-coded bricks. Verify accuracy by counting each piece once aloud, pointing to every unit to prevent repeats or skips.
Include quick tasks such as finding a missing part: present a group of 7 as 3 and an unknown set, and prompt students to supply 4 to balance the total. Keep sums within 10 for beginners and extend toward 20 for confident groups.
Add sequencing drills where children arrange models showing 1 through 10 in ascending order, then reverse the strip to practise descending order. Encourage self-checking by comparing model height or length.
Finish each page with a brief challenge like combining two piles and recording the total, then splitting the same total into different pairs. This builds flexible thinking about quantities without adding extra symbols or complex layout.
Teaching 0–20 Counting with Interlocking Bricks
Group single cubes into tens and ones using two colours: build a rod of ten, then attach up to nine extra units. Ask learners to point and say each digit aloud from 0 to twenty, touching every cube once to anchor one-to-one correspondence.
Rotate roles during practice: one child builds a tower showing a target value such as fourteen, while a partner checks by separating a ten-rod and four loose units. Record each value on a line beside the model to connect quantity with written digit symbols.
Include quick error-spotting drills. Present a tower labelled “16” that actually holds fifteen cubes and invite students to adjust the model. This sharpens careful counting and discourages skipping or double-counting.
Finish with build-and-break routines. Learners assemble a total like nineteen, then break it into different pairs (10+9, 12+7, 15+4). This repeated regrouping strengthens place value sense while keeping totals within twenty.
Adding and Place Value Using Grid Arrays
Use a ten-by-ten grid and coloured cubes to model totals up to one hundred. Fill each row from left to right while learners say each digit aloud, then mark completed tens with a different colour to make regrouping visible.
- Build 27 by filling two full rows and seven extra spaces. Ask students to point to each filled square and read the value: “ten, twenty, twenty-one … twenty-seven”.
- Add 15 by placing one full row and five more squares. Learners recount the new total together, confirming that 27 + 15 reaches 42.
- Highlight tens and ones. Circle four full rows to show 40, then isolate the remaining two single squares for the ones place.
Switch to partial grids for quick practice. Provide a page where some rows are already filled. Learners complete the missing spaces, write the matching digit, and decompose each total into tens and ones (for example, 68 = 60 + 8).
- Ask students to predict whether a sum will create a new full row before adding. This strengthens regrouping without jumping steps.
- Include subtraction by removing cubes from the right end of a row, maintaining the left-to-right count to avoid skipping.
- Track accuracy with a small checklist: correct total, correct tens count, correct ones count.
Close each session with a short challenge such as “build 54 in two different colour patterns” so learners must show the same quantity while preserving place value structure within the grid.
