Teen numbers are hard! They don't "sound like they look". For example ,when say 14 you hear the "four" first but it is written last. So we are learning that the teen numbers are like teenagers...they don't follow the rules. They always think of number 1 first. 😊. Sounds silly but it helps them remember when they write a number like 14 to not write 41.
We have made sets and represented ( with place value, tens frame, and number line) the numbers 11 & 12 this week!
