Sample questions

A few real prompts from the game to help you choose an activity for your class.

  1. Put the numbers in order from smallest to largest.

    • 1099
    • 1190
    • 1901
    • 1910
    Read the explanation

    Compare place by place from the left.

  2. Put the fractions in order from largest to smallest.

    • 1/2
    • 1/3
    • 1/5
    • 1/8
    Read the explanation

    The tops match; the smaller the bottom, the larger the fraction.

  3. Put the steps of multiplying a two-digit number in order.

    • carry if you need to
    • line up the columns
    • multiply the ones
    • multiply the tens and add the carry
    Read the explanation

    Multiply the ones first, because a carry from them affects the next place.

Game teaching guide

What children will practise

Order four-digit numbers made of the same digits, order unit fractions largest first, put the steps of column multiplication in order, and order units of time from shortest to longest.

What's in the worksheet

4 ordering questions - 1099, 1190, 1901, 1910 smallest to largest - 1/2, 1/3, 1/5, 1/8 largest to smallest - Line up the columns, multiply the ones, carry if needed, multiply the tens and add the carry - Second, minute, hour, day

How to use it in class

Use to review several topics in one lesson, about 5 minutes, team mode. - For 1099 to 1910, have teams write the numbers in a place-value chart first - After the multiplication steps, teams work 47 × 6 on paper following them - The fractions go largest first, the reverse of many sets; read the instruction first - Play it linked to the class to record results in the mark book

Common sticking points

- Swapping 1190 and 1901, which use the same digits. Compare the hundreds, 1 and 9 - Ordering the fractions 1/8, 1/5, 1/3, 1/2, out of smallest-first habit or thinking a bigger bottom number means bigger - Putting "multiply the tens" before "multiply the ones", reading numbers from the left

Play together first, then build on it with a worksheet for the same level.
