![]() Once students have a solid understanding of using place value and number sense to compare numbers, then I introduce the symbols. Tip 3: Teach the symbols for Comparing Numbers I always have students underline the digit that determines the greater number. 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.

These pages help break down standard language, lay out the grade-appropriate level of rigor for each concept, and offer a variety of suggestions for activities (lesson seeds) that help students achieve their learning targets. If you are interested in getting ideas on how to plan a robust standards-aligned telling time lesson, we recommend checking out Instructure's recommendations for common core standards 1.NBT.B.2, and 2.NBT.4. Look into the relevant standards here, or dig deeper into Inequality mathmatics here. This song targets TEKS and Common Core learning standards from both 1st Grade and 2nd Grade. Or write a line underneath the “less than” sign,Īnd "less than or equal to" is the name of this design. "greater than or equal to" is how the sign is defined. If there's a line underneath the “greater than” sign, Neither is greater or less it's a perfect tie, The gator wants to eat, but he can't decide. Now the numbers are the same on both sides. Nine’s the greatest ones place, so he takes a big bite. The gator needs (or finds) the greater value on the number line. The gator needs to eat the one with the greater value.įive’s the greatest tens place, so he takes a big bite. He looks at the place values from left to right Įight’s the greatest hundreds place, so he takes a big bite. The gator eats the one that's worth more. On a somewhat unrelated side note, Slater has an Australian accent and will get quite chatty towards the end of this comparing numbers song! Less Than Greater Than Lyrics: ![]() Slater is a very hungry alligator that is always comparing numbers and eating the number that is greater! Watch him walk around his hometown marsh and swamp in this greater than less than video as he eats human food and goes apple picking for the largest apple he can find. ![]()
