During our math time this week we continued to study **LARGE, TWO-DIGIT** numbers. In particular, we used the greater than, less than, and equal to symbols ( >, <, = ) to compare these numbers. When we compare numbers, we stressed the importance of building each number with ten sticks and ones to easily identify which number has more tens. If both numbers have the same amount of tens, then we can compare the ones to find the greater number. Our first graders quickly noticed that the greater than and less than signs look like a “hungry mouth” ready to gobble up which ever number is greatest.

Just be careful… don’t let number like: 29 & 92 or 45 & 54 or 78 & 87 – trick you!!! Build those numbers and pay attention to the tens!!! Please review this concept with your first grader, if you notice him or her getting a little confused on the homework.

This week we also practiced adding ones numbers (1, 2, 3, 4, 5, 6, 7, 8, 9) together, and tens numbers (10, 20, 30, 40, 50, 60, 70, 80, 90) together. Our first graders worked hard to notice which numbers they were working with so they could accurately represent each equation. In order to prove our work, we used ten sticks and circles to help us find the missing total.
