First graders' fluidity with comparing numbers is an important building block for the higher-level math concepts to come in the later grades. You can give first graders a leg up with this lesson, featuring guided instruction and practice problems in comparing numbers. Once kids get through this lesson, you can download and print the suggested comparing numbers worksheets in order to provide even more opprotunities for practice.
First grade mathematicians will be working this year on number sense in order to improve their understanding of the relationship between numbers and their ability to do mental math. This guided lesson will help strengthen this important skill with targeted instruction and plenty of real-world practice problems. Once the lesson is finished, you can extend learning with the suggested number sense worksheets.
This lesson is a continuation of place value practice, and offers more instruction on identifying tens and ones in 2-digit numbers. Once first graders are able to quickly identify place value they are then able to understand on a deeper level what larger numbers actually mean. This is crucial for the math fluency that will support higher-level concepts in the later grades.
Skip counting by 10s is quite the fascination with young learners, who are eager to reach 100. After mastering skip counting by 2s and 5s, let your students continue to develop their understanding of skip counting by working with 10s. The activities outlined below are a great starting place for children trying to learn how to skip count, whether by 2s, 5s, or 10s.
Approaching numbers from many directions is one of the ways we teach children and early learners number sense. One approach that is commonly taught is skip counting by tens.
While it may seem arbitrary, skip counting by tens has a number of benefits for students. It allows them to see patterns in numbers. When counting the whole tens (10, 20, 30…) they see that the first digit of each number is the same as when they simply count to ten and the second digit of each number is zero.
Understanding this pattern will allow them to count by tens without even when they start with a number that is not a multiple of ten. If they understand that only the first digit changes, they will understand that regardless of what number they start with, the digit in the ones place will not change.
Skip counting by tens also lays the foundation for early multiplication. When students understand that the fifth number you reach when skip counting by ten is fifty, and five times ten is fifty, they can expand on that concept to find other products when multiplying by ten.
Using a 100s chart is one way to help students identify the patterns. They will see that, if each row in the chart has 10 digits, regardless of where they start, skip counting will just be counting down each column.
Practicing with the resources provided above by Education.com may help students learn to skip count by tens consistently and gain a foundation in number sense that teachers can build on in the future.
