Task Card Use #7
Use for after school tutor sessions.
Students won’t feel overwhelmed when
working on one card at a time.

Introduction
Task cards are a great tool for you to shake up how chapter review is done in your classroom. Students will LOVE the variety in which task cards can be used, such as in pairs or small groups, team games (Jeopardy style), or even as part of daily class work. The reason they are so effective is because there is only ONE task per card, allowing students to focus on that single task until they have successfully completed it.
This set of Atom and the Periodic Table task cards are meant to be copied, cut-out and laminated. If this is your first time using task cards, I would suggest making several sets and storing each set in either ziploc baggies, envelopes, or punch a hole in corner and put set on a ring. Whatever way you decide to keep your cards, it's important to make sure they are accessible to students. By doing this, fast-finishing students can always grab a set and take back to seat, or when students are in lab groups I would have them complete five cards as part of their pre-lab, then they could begin once all answers are correct.
I've also included an answer sheet in this download so students can work on one card at a time, then rotate cards among small groups or even entire classroom. I give each student a card and set a timer, once timer goes off, students pass cards and work on next problem. Once cards have passed through all students, we review answers then make corrections where necessary.
I would highly suggest researching all the ways you can use your new set of task cards - the possibilities are endless!! Because I'm such a fan of game-show review I've made a set of task cards that have numbered point values so you can place on the backside of task cards placed in a pocket chart. Teams can choose cards by point value and answer cards correctly for the win! Check my store for this FREE download.
Enjoy the task cards, and as always, I encourage you to contact me with any comments, questions or concerns. Have fun getting down to the Nitty Gritty in Science Review! - Erica Colón
