First graders hit the ground running in 2020! They began a math unit on place value, focusing on the tens and ones places. Although this is a difficult concept, they are building understanding through several games. Using base-ten blocks, students have been playing games where they actually trade ten-unit cubes for a long, or ten cubes fused together. They also played guessing games where they used their knowledge of place value to guess a mystery number. In a fun, engaging atmosphere, students built some serious understanding of tens units by creating groups of ten.
