Ten bones are hidden in the squares of a blank 1-100 grid. Students are given the numbers of the squares one at a time. They attempt to locate the numbers in the hundreds chart and find all 10 bones within 60 seconds. Numbers of the incorrectly guessed squares are left in place to help with the search. The game helps students understand the structure and patterns of our base-10 number system. Children can be encouraged to make use of a found bone to locate the next one.
This is an excellent activity to get students to utilize a hundreds chart and build number sense. It is a short game which will easily keep young students engaged.
100-grid; imagine that! By Uncle Bob on 04/19/2012 - 10:18
This game works well. When you choose an incorrect location you see the number there and can track toward the correct position. I also found out that you can continue to find bones after the minute is up. This frees you from time pressure. Great workout for the mind's eye in perceiving this spatial orientation of our decimal whole numbers.
