We have been underway with our math unit, Numbers and Operations in Base Ten! We have been focusing on hundreds, tens, and ones. In class, we have been working to trade in 10 units (ones) for a rod (ten), 10 rods for 1 flat (a hundred) and so on! In order to practice place value and expanded form (stretch the number out like an elastic), we used Cheeze-Its (as hundreds), thin pretzels (as tens) and cheerios (as ones).
Throughout the year we will practice time and money. I try to incorporate these skills weekly in order to develop a deep understanding by the end of second grade. The students practiced time by playing "Bee on Time". I love this game because it really makes them stop and think about the hour and minute hand separately.
