Hide and Seek Numbers

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Activity

In these knowledge-based activities, students are encouraged to think about how numbers on a hundreds board relate to each other. Spend some time exploring the hundreds board with all the numbers visible before you mask the numbers. Let the students discover the number patterns as numbers go up a row (– 10) and down a row (+ 10) and horizontally to the left (– 1) and to the right (+ 1). Encourage the students to skip-count in tens for numbers other than 10, for example,
12, 16, or 13, both forwards and backwards. Explore the charts in your thousands book (Material Master 4-7) as an extension and let the students discover that the patterns are the same as for hundreds.


Activity One

The students will probably be able to name the number to the right (+1) most easily, so start with that one, followed by the number to the left (–1), then down (+10), and finally up (–10).


Activity Two

This activity can also be done on smaller individual hundreds charts and extended to any chart in the thousands book so that the students are working with numbers up to 1 000. As an extension, give the students other cardboard shapes to cover the hundreds board, for example:
