Decimals Diner

What your child will figure out

• Read, build, and locate decimals through thousandths in money and measurement contexts.
• Connect equivalent forms, then compare and order decimals from the greatest place toward the smallest.
• Add and subtract decimal amounts by aligning decimal points and equal place-value columns.
• Round, estimate, and scale decimals by reasoning about how each digit's place value changes.

The levels

1. Build the milkshake price

   Predict and build $3.40, observe dollars/dimes/cents, and explain the tenths and hundredths places.

2. Park the pie on the line

   Place $3.65 between neighbouring tenths and explain that hundredths subdivide a tenth.

3. Run the breakfast rail

   Compare then order $2.08, $2.35, and $2.50 using aligned place values.

4. Close the booth check

   Add $4.75 and $2.80 by aligning the decimal points.

5. Make change at the counter

   Subtract $3.65 from $10.00 by aligning places and regrouping.

6. Post the rounded menu price

   Round $8.67 to the nearest tenth using the hundredths digit as evidence.

7. Estimate the family booth

   Estimate a two-item total by rounding both addends to the nearest dollar.

8. Pour the shake exactly

   Locate 1.375 L between neighbouring hundredths and interpret thousandths.

9. Sort the delivery weights

   Order four kilogram measures with mixed written precision.

10. Scale the sauce batch

    Multiply 0.048 L by 100 using place-value shifts rather than a point-moving rule.

11. Total the party table

    Add three prices with regrouping across hundredths, tenths, and ones.

12. Save the last shake

    Transfer the point-anchor idea to subtract thousandths in a non-money capacity context.
