Guess My Number - Hundreds Chart Puzzle Pack
This differentiated puzzle pack engages students in logical thinking and number identification using clues and hundreds charts. Students solve "Guess My Number" challenges based on place value, number properties, and addition/subtraction patterns.
Includes:
- 10 clue-based puzzle worksheets
- Matching 0–1000 Hundreds Charts to support visual scanning
- Clues requiring knowledge of odd/even, greater than/less than, place value, and digit sums
- Scaffolded difficulty moving from 2-digit to 4-digit ranges
Students use reasoning and elimination skills to solve number mysteries, making this a fun and brain-stretching numeracy activity.
Learning goals
- We are learning to recognise, model, represent and order numbers to at least 1000.
- We are learning to recognise halves, quarters and eighths of an object and to understand that a group of objects can be separated to show halves, quarters and eighths of the group.
- We are learning to recognise, model, represent and order numbers to at least 10 000.
- We are learning to partition, rearrange and regroup numbers to 10 000 using place value groupings.
- We are learning to recognise, model, represent and order numbers to at least tens of thousands.
- We are learning to make connections between fractions and decimals to tenths and hundredths.
- We are learning to read, write, name and order numbers to at least 1000 using concrete and virtual materials, numerals and number lines.
- We are learning to recognise halves, quarters and eighths of a whole and connect halves, quarters and eighths through repeated halving.
- We are learning to add and subtract two-and three-digit numbers using place value groupings.
- We are learning to recognise and extend place value to tenths and hundredths use decimal notation to name and represent decimals.
