This seems like it would be a great activity but I wonder if students would have a hard time finding all the bones before the time runs out. Has anyone tried this with K-1 students?
Once students have mastered this activity in grade grade 1, then they will be ready to move on to "Number Square Puzzle: 10 Missing Numbers " in grade 2 and 3. This activity allows the teachers to alter the grid to have a new starting value, to skip count, and to be smaller or larger. Then students must identify the locations of the ten numbers shown on cards. You can set it up to begin at 1 and count by 1's until 100, if you want to use it still with 1st or 2nd grade.
I haven't used this with K-1 students, but I would be interested to know if they had enough time or got frustrated. I feel like 1st graders should be able to complete it in the time allotted. I would also like to know if anyone has tried this on a tablet, I think this would lend itself to individual practice without the complications of the computer mouse.
I have used this feature in both K and 1 classes. I've used it on an interactive white board and on the computer. It has been great at the K level to boost the skills of those kids who are familiar with the hundred's chart. They love trying to beat the clock. However... really the clock isn't even necessary. If you let it run out you can still play the game with all the features (showing the numbers and resetting the board) and kids are able to find all of the bones with no time limit. I used it in first grade with a student who had great familiarity with the hundred's chart, but was very slow at processing through his thinking. The time limit was great for him, but then he still continued after the timer went off to get that extra practice. It was amazing at how his speed picked up with each new turn. I highly recommend this game.
This is great information. I think this will be really helpful for children learning to count up and count down while having fun. Since the time factor isn't an issue, it should be a really useful resource!
I have also seen this used on an IWB. It really was an engaging way for students to look for patterns. The student discussion about how they locate the desired number is very rich. I am sure that this would be an engaging came for students on their own, but when working together on an IWB, it really fosters great math talk. One of my favorite sites to share with teachers just getting started with IWB.
I'm glad to hear of the usefulness of Dog/Bone. Visualizing what is not there is an inestimable asset for mathematics. Mathlanding has cataloged other 100-grid activities. I like 'Hundred Square.' Although not interactive, it involves visualizing the spatial transformation of the grid (onto the reverse side of the handout). Another recent catalog addition is 'Jigsaw' which asks students to assemble the 100-grid or a multiplication table. Higher levels of difficulty can be very challenging.
