Building Number Sense

First graders are busy identifying, comparing, visualizing, adding and subtracting numbers during math workshop. They played Compare and Dot Compare this week. They practiced telling which card was more and how they knew it was more. 

They played Plus or Minus 1 Bingo with partners. They developed fluency with adding and subtracting 1 with numbers to 10. 

They also played Quick Images. They saw an arrangement of dots flashed on the screen for 5 seconds and had to make a mental image of it. Then they had to build the image from memory when it was covered. We talked about patterns they saw to help them remember the image.
