## 25 Things to do with the Hundreds Grid in a Guided Math Group or Math Center

*25 Things to do with the Hundreds Board*

The hundreds board is a great tool for teaching a variety of math concepts. Some boards start with 0 and others start with 1. Every student should have their own number grid. Remember in terms of differentiation, everybody is not necessarily on the same page. For example, some students might be working on a number board that goes up to 20 while another could be working on a number grid that goes up to 200. Number grids are great for teaching a variety of concepts including addition and subtraction strategies, reading number words and ordering numbers. See the list below for some ideas.

*1. **Adding +1*

*2. **Subtracting -1*

*3. **Adding + 10 (http://www.ictgames.com/100huntplus10.html)*

*4. **Subtracting +10*

*5. **Teaching compensation with +8 facts*

*6. **Teach compensation with + 9 facts*

*7. *** Reading Number Words. **Students pull a number card and mark that number word on the grid.First person to get 4 in a row vertically, horizontally, or diagonally wins. Each player uses their own mat.

*8. *** Number Hunt.** Teacher calls out a numeral and the students find it. This is a great way to reinforce vocabulary because the teacher can call out numerals such as 10 less than 25 or 1 more than 64 etc. Also, the teacher can call out the numeral in terms of place value. For example, find the number that has 2 tens and 7 ones.

*9. **Number Grid Puzzles*

*10. **Fill in the Missing Numbers –*

* *

*Take a number grid and white out some of the numbers. Do this according to readiness levels- so some students have 5 numbers whited out while others have 25 missing. Then put this grid in a sheet protector and have the students fill in the missing numbers.*

*18. *** Numbergrid races.** Students race against themselves or others to put the hundred board back together. This can be cut up into various degrees of difficulty. For example, some puzzles can be cut into horizontal strips, others into vertical strips, others into squares or rectangles and still others into varying odd shapes.

*19. **Race to 100*

*20. **Race from 100*

*21. **Highlight odd and even numbers*

*24. **Multiple patterns ** *

*25. *** Money **– The hundred board is great for teaching money. Start by having students landmark the nickels, dimes and quarters and then give them problems where they have to use these landmarks to add money.
