A good number prompt does not need much setup. Sometimes the class just needs one fresh number to read, compare, rename or place into a larger discussion.
The Daily Maths Review random number generator lets teachers choose a digit length, choose how many numbers to show, generate a new set quickly and display the numbers in classroom-friendly fonts.
Start with one clear task
Before generating the numbers, decide what students will do with them. A random number can support reading aloud, comparing, ordering, partitioning, rounding or estimating, but the prompt is stronger when the action is explicit.
- Use one number when students are practising reading or renaming.
- Use two numbers for greater than, less than and difference questions.
- Use three or more numbers for ordering and sorting.
- Use larger digit lengths before moving into place value houses or number-line models.
Ask students to explain the number
After a number appears, ask students what each digit is worth. Then ask for another way to write the same number, such as expanded form, words, rounded form or a nearby benchmark.
Generate three four-digit numbers, ask students to order them, then choose one number and rename it in expanded form.
Move from prompt to model
If students can compare the generated numbers but struggle to explain why, move into a visual tool. Place value houses can show the digit structure, while the number line tool can show relative size and position.
