I only reveal the numbers we have worked on. Each day my teachers helper gets to whisper a number in my ear. Then he/she will call on students to guess what number was chosen. I use little sticky notes to cover up the numbers. When the number is guessed, the helper writes the number on the board. I am never allowed to miss this activity, and my kids are learning. 👏
The picture above is part of my jungle/safari math centers. I will have it in my stores early this week, this is just one of the ideas. Hope you all check it out!
