Teachers : For the best experience you will need use two screens. One to present to the students and one that only the teacher can see.
Teacher Screen: Access the “teacher dashboard” on your computer.
Presentation Screen: If you are in class together, present the lesson to your smartboard. If you are wanting to go over the answers, just do a mouse click on the presentation (not the teacher dashboard)
Note: You can present the lesson to students (via screenshare or smartboard). If you are teaching virtually (not in person) then students can have two tabs open on one screen and toggle between your presentation tab, and their student peardeck tab.

I can multiply by 7 and 9.
Common Core Standards: Grade 3
Multiply and divide within 100.
3.OA.C.7
Common Core: Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
