Teaching number sense gives kids a deeper understanding of our number system, which will in turn prepare them for the algebraic equations to come in the upper elementary grades and middle school. You can create a strong foundational knowledge of number sense with this guided lesson, which provides third graders with targeted instruction and exercises designed by our team of curriculum experts.

Number Sense 2

Once kindergarteners understand the concept of more and less, they will move on to basic subtraction with single-digit numbers. This can be a tricky concept for kids to master. You can help this transition with these exercises that aim to give kids targeted practice in subtraction. Once the guided lesson is finished, you can support learning further with the accompanying subtraction worksheets.

Subtraction 1

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.

Number Sense 1

This year, first graders will be introduced to place value and our base 10 number system, usually by starting with 2-digit numbers (100 or less). This guided lesson helps introduce place value to first graders through instruction and examples targeted to this skill. If your child finishes the lesson and needs more practice with place value, download and print the accompanying worksheets suggested by our curriculum team.

Place Value 1

This year, third graders will build a stronger understanding of division. This guided lesson uses the repeated subtraction strategy as a way of teaching division. The lesson shows how division problems can be solved by repeatedly subtracting the same number (the divisor). Not only does this help students solve division problems, but it also builds a conceptual understanding of division. For more practice, check out the suggested division worksheets.

Division 1

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.
