Reflection: Transitions Common Ionization States - Section 4: Partners Activity

 

I was having trouble getting my students to move into pairs quickly.  The transitions began dragging out as students either were having trouble finding a partner or large groups of friends wanted to "partner" up together in groups of five or six.  I needed a solution and remembered the "clock appointment" partners strategy I had learned in a workshop years ago.  I never needed to use something like this with past classes, but this year I noticed that a lot of time was being lost during this particular type of transition (pairing up).

This video explains what I came up with (a modification of clock partners) and how to have students use it to determine partners.  It took about 20 full minutes to complete, between explaining how to set it up, having students work to complete it, and then troubleshooting afterwards for students who completed it incorrectly.  Watch for students to sign each others' sheets on different directions (BAD) instead of the same direction (GOOD).  A copy of the document I used is also attached here: Compass Partners Sheet.

Common Ionization States

Unit 2: Electron Configuration & Bonding
Lesson 4 of 9

Objective: SWBAT predict the ionization state for elements based on their tendencies to gain or lose electrons to obtain a full valence shell of electrons.

Big Idea: Elements that gain or lose electrons to obtain stability have predictable ionic charges based on their position on the periodic table.
