First graders continue to develop their understanding of place value and our base-ten number system. This week, they are working to compare and order 2 two-digit numbers based on the values of the tens and ones digits and to record the results of these comparisons with the symbols >, <, or =. They are noticing that if a two-digit number has more tens it will be greater than a number with fewer tens, no matter how many ones there are. This is true because we know that the value of the digit in the ones place will always be less than 1 ten because the place value system only allows up to 9 ones.
