Ionic bonding with monovalent, polyvalent, and polyatomic ions used to have my students' heads spinning! Now, after I teach them how to "criss-cross" the charges on the ions to make subscripts, I send them on their way doing these ionic bonding stations to give them extensive practice without having to do a boring worksheet.
These cubes will help your students practice writing formulas for and naming various ionic compounds!
There are six cube patterns (3 cation cubes and 3 anion cubes) containing various monovalent, polyvalent, and polyatomic ions. This provides differentiation within the activity!
The least amount of prep for you for this activity is to set up stations.
There will be 9 stations, which will provide every possible combination of cation and anion for your students to practice.
Print three sets of each of the Cation sheets (I print these on bright pink paper), and print three sets of each of the Anion sheets (I print these on bright purple paper). So you should have a total of 18 pages (9 Cation sheets and 9 Anion sheets).
Cut out the blocks and fold on the lines to form cubes. Tape edges together. With tape on all six edges, these blocks are sturdy! I don’t use laminated paper and they hold up fine. Thicker cardstock may work even better.
Now, pair your Cation blocks with the Anion blocks, forming all 9 combinations.
A student worksheet is provided for writing down the ions, formulas, and compound names. There is an answer key block for each of the 324 combinations so your students can check/grade their answers when they finish the 9 stations.
Students are engaged because they get to roll the dice and see what compound they have to make, and I find that my students do this activity and are able to verbalize where they are struggling ("I don't understand how to work with polyatomic ions"). The many combinations of ions is embedded differentiation for your lesson plans!
