These dice were designed for my high school chemistry class. The point is to help students practice balancing charges of cations and anions by making a balanced ionic compound out of the results of the dice roll.
The dice are included both as a pair, as individual dice, and the original blender file, in case you wish to make any edits to suit your needs.
They can be used in groups or to give each students a chance to practice the many combinations. You can also have students practice naming the resulting compound, including the variable iron ions.
If there is anything you can suggest to be included with the dice, let me know!
For standard 16mm dice, print at 800% scale, no raft or brim necessary. Jumbo dice were printed WITH supports at 2400% scale.
Overview and Background
In working towards more engaging instruction and practice for students in my high school NYS Regents Chemistry class, I designed these dice to give students an opportunity to work collectively to practice balancing and naming ionic compounds.
Lesson Plan and Activity
Objectives: Students will be able to balance an ionic compound so that positive and negative charges are equal between anions and cations. Students will be able to name ionic compounds, both binary and ternary, as well as with transition metals using the stock system.
Procedure: Students are to form groups of no more than 4, assigning one student as the record keeper. Each group will need 1 set of dice, a writing utensil, and a piece of paper. On a 3 minute timer, students are to roll the dice, write the resulting combination as a balanced chemical formula, name the compound, and repeat until the 3 minutes are up. At the 3 minute timer, record keepers are to run to the instructor to turn in the paper to be checked while the next round begins. The most correct answers (formula and name are separate) from a group in a round wins the round (tie goes to the one who gets to the instructor earliest). After all rounds (I will be doing 7 rounds, with 6 to 7 groups) are complete, points and the winner are announced.
-1 set of dice per student group
-1 writing untensil
