Mr. Lake on Instagram: "We LOVE playing this mystery number game. I pick a number between 1–100. Students guess. I say greater than or less than. We move the chips and narrow the range each time. It builds number sense, comparison, and place value without a worksheet. They stay locked in the WHOLE time. 💬 Comment “game” for the chart. #elementaryteacher #primaryteacher #iteachkindergarten #mathgames"
