The sessions have 1000’s of online and offline activities that can be completed in as little as ten minutes, and teach students using videos, interaction, poems, songs, and digital notebooks.

This short video and interactive assessment activity is designed to teach second graders about fact families (numbers to 1,000).

This short video and interactive assessment activity is designed to teach third graders about fact families (numbers to 1,000).

This task allows students to relate addition and subtraction problems to money in a context that introduces the concept of scarcity.

This short video and interactive assessment activity is designed to teach third graders about filling in the missing + or - sign.

This task asks students to solve addition and subtraction equations with different structures so that they are able to see the connections between addition and subtraction more easily.

Challenge first graders with math problems that will help them master first-grade math skills! In first grade, students learn about money, time, measurements, and patterns. Building a solid number sense is important for students in this age range. First graders learn to recognize patterns and sort objects by color, shape, and function. They will also learn to recognize and differentiate between two-dimensional and three-dimensional geometric shapes like squares, triangles, cones, and cylinders. By the end of first grade, students should be able to count to one hundred by ones, twos, fives, and tens. They will also be introduced to the concepts of more and less, and have an opportunity to work with simple graphs.

Now that your child has mastered numbers and counting, it's time to take things to the next level with our first-grade math worksheets! Keep students' math minds sharp with daily first-grade math and critical thinking practice worksheets as well as daily homework and practice pages. Weekly word problems, first-grade algebra and geometry, counting and comparing numbers, and introduction to addition are just some of the engaging, no-prep first-grade math worksheets available on this page.

Math Game Time offers a variety of games, videos, and printable worksheets tailored for K-6 and middle schoolers to enhance their math skills. With focused videos on specific topics and kid-appropriate games, it's an ideal resource for practicing math skills.

Fun Kids Online Math Games (Sheppard Software is a great resource for teachers looking for new ways to differentiate. The games offered on this site have many levels, so no matter what stage your student is at, he or she can still practice and have fun! The games are geared towards elementary and middle school students.

The content and games for this website were created with these goals in mind:
1) To add sound and visual effects to make learning fun and more memorable.
2) To design games with many difficulty levels so that players will continue to be challenged no matter how far they progress.
3) To provide games that will exercise players' brains.

NOTE: although some of the money activities are using USD, many of the activities are generic and can be used to enhance the understanding of working with money.

In this first module of Grade 1, students make significant progress towards fluency with addition and subtraction of numbers to 10 as they are presented with opportunities intended to advance them from counting all to counting on which leads many students then to decomposing and composing addends and total amounts.

Module 2 serves as a bridge from students' prior work with problem solving within 10 to work within 100 as students begin to solve addition and subtraction problems involving teen numbers. Students go beyond the Level 2 strategies of counting on and counting back as they learn Level 3 strategies informally called "make ten" or "take from ten."

Module 4 builds upon Module 2’s work with place value within 20, now focusing on the role of place value in the addition and subtraction of numbers to 40.  Students study, organize, and manipulate numbers within 40.  They compare quantities and begin using the symbols for greater than (>) and less than (<).  Addition and subtraction of tens is another focus of this module as is the use of familiar strategies to add two-digit and single-digit numbers within 40.  Near the end of the module, the focus moves to new ways to represent larger quantities and adding like place value units as students add two-digit numbers.

In Module 4, students develop place value strategies to fluently add and subtract within 100; they represent and solve one- and two-step word problems of varying types within 100; and they develop conceptual understanding of addition and subtraction of multi-digit numbers within 200.  Using a concrete to pictorial to abstract approach, students use manipulatives and math drawings to develop an understanding of the composition and decomposition of units, and they relate these representations to the standard algorithm for addition and subtraction.

In Module 4, students developed addition and subtraction fluency within 100 and began developing conceptual understanding of the standard algorithm via place value strategies. In Module 5, students build upon their mastery of renaming place value units and extend their work with conceptual understanding of the addition and subtraction algorithms to numbers within 1,000, always with the option of modeling with materials or drawings. Throughout the module, students continue to focus on strengthening and deepening conceptual understanding and fluency.
