Read & Write Focus: The Number 12 - As you know, reading and writing teen numbers can be tricky—they don’t follow the same pattern as most other numbers. This lesson is a great continuation in our sequence on reading and writing 2-digit numbers. We’ve previously focused on multiples of ten—like 30—where the 3 in the tens place and 0 in the ones place make the value clear. Now, we shift our attention to those confusing teen numbers. Our resources are designed to help students make sense of this.
