![]() We practice building numbers with base 10 blocks and using place value charts. For example, in the numbers 34 and 56, the digit in the tens place is greater in 56, which makes it the greater number. Students can compare the digits in each number to determine which one is greater. If the 10s place is the same, we move next door and look at the 1s. We compare the digits and learn that the number that has more 10s will be the larger number. When comparing For 2-digit numbers, we start with the 10s place. We always begin with the highest place value. I model for students how to use place value to compare. This will be extremely important, once we start using comparison symbols! Tip 2: Use Place Value to teach Comparing NumbersĪfter introducing how to compare numbers and using greater than/ less than vocabulary, we then start to work with 2-digit numbers. We practice reading comparisons from left to right. At this point we are just practicing with the words. I then teach my students comparing numbers vocabulary: greater than, less than, and equal to. Students can see that the further to the right a number is on the number line, the greater it is. Number lines can be a helpful visual tool for comparing numbers. We practice using number lines, 120 charts, and pictures to determine which numbers are bigger and which are smaller. We practice using number sense to determine which numbers are bigger or smaller and then using comparison vocabulary – greater than, less than, and equal to – to describe numbers. In this post, I will share exactly how I teach comparing numbers in 1st grade and share some hands-on comparing numbers activities! You can find all the activities for comparing numbers in my Place Value Guided Math Unit here! Tip 1: Don’t Teach the Comparison Symbols Right Away!īefore I introduce comparing symbols to my students, I want students to have a concrete understanding of how we compare numbers. I like to begin my comparing numbers unit, right after our place value unit! You can read more about our Place Value Unit here! In order to compare 2-digit numbers, 1st graders need to have solid number sense and place value understanding. By the end of the year, students should be able to compare two-digit numbers and determine which one is greater or less than the other. The students return their bugs and repeat.Comparing Numbers is an important skill that we teach in first grade.The student with the greater number wins.Partners read the inequality sentence together.Students place the bugs on the Alligator Greater Than Mat in the correct place to make the inequality sentence true so the alligator eats the greater number.On the count of three, each student reveals his/her bug card and compares the numbers.Students each choose a bug from around the room and bring it back to their battle mat.Scatter the two-digit bug cards around the room.Pair students and have each partnership get an Alligator Greater Than Mat. (printable from ).Review one of the bug battle visuals from yesterday.Practice writing >, =, or Build each bug's number with base 10 blocks to support conceptual understanding of which number is greater. ![]() Have students record the numbers for each bug on their individual whiteboard. ![]()
