Use this lesson to review three-digit addition strategies including base-ten drawings, number lines, and the standard algorithm.

Students will get a chance to use multiple methods to compare three-digit numbers. They will also get practice using greater than and less than symbols to show their answers.

Give your students a conceptual understanding of three-digit addition with this lesson focused on base-ten blocks and drawings.

Students will get to explore three-digit numbers through base-ten blocks and written form. Students will get plenty of practice identifying the place values of a number both individually and with the class.

Let’s start building numbers! Just as building skyscrapers is a visual representation of mathematics, students will use the visual representation of base-ten blocks to add—or build—onto a two-digit number.

Do your students ever want to just hurry and finish their homework? Your students can use the number line jumping strategy to quickly add two-digit numbers and show their understanding of place value and expanded form in the process.

Who doesn’t like to spend money and plan parties? Students will subtract two-digit numbers as they calculate the remaining money for their party supplies. They will subtract in multiples of ten and focus on place value.

Can you break a ten? An everyday exchange of money can help students think about regrouping to subtract. Students will use bundled popsicle sticks to see how values grouped into tens can be regrouped into ones to allow us to subtract.

In this lesson, students will learn how to add a one-digit number to a two-digit number. This will help students build upon the skills needed for regrouping larger numbers.

Help your students make sense of the greater than, less than and equal to in this interactive lesson! Your students will have opportunities to compare either two-digit or three-digit numbers.

In this lesson, your students will compare numbers to one thousand using place value charts and symbols. Your students will love practicing with numbers!

Dive into understanding place value by using place value disks to represent and compare numbers.

Double-digit trouble? No problem! Your students will practice their decomposing and regrouping skills in this lesson.

Start your students on subtracting three-digit numbers with this lesson that breaks the problems down by place values!

Teach your students to use skip counting as a strategy to multiply two single-digit factors.

In this lesson, students will add three-digit numbers using expanded form addition and standard algorithm addition. They'll explain their answers and highlight the steps for each of the strategies.

10, 20, 30, and up! In this lesson, students learn strategies for multiplying one-digit numbers by multiples of ten (10 through 90) through practice problems and playing a fun, hands-on game.

Freshen up on your understanding of division word problems with long division and one-digit divisors! Use this lesson to help students identify key division terms and solve word problems.

What exactly does the number 97 mean? How about 454? In this lesson, students explore how two-digit numbers are made up of tens and ones. Then they use this understanding to subtract numbers within 1000.

Expand on your students' knowledge of base ten numbers with this lesson that introduces the students to the place and value of digits within a number.

Your students will “hop their way” into understanding place value with this fun and active game! In this lesson, they will learn that changing the order of the digits in a number changes its value.

Tap into students' metacognitive skills and get them to think about their thinking! This lesson encourages students to pay attention to the strategies they use while supporting math fluency!

Help your students subtract with confidence by sharing two different strategies. Use this lesson to build on students’ understanding of subtraction and to evaluate this key skill.

Get your students excited about money! Have them make connections between their prior knowledge of base-ten numerals and one, ten, and hundred dollar bills.

Help your students practice place value with this fun, hands-on base-ten block game. Neighborhood block teams compete to win points as they work together to show expanded numbers.

This bear-y fun lesson will help your students understand addition and subtraction and reward their efforts with a sweet treat!

Now that your first graders are able to count consecutively, introduce them to the tens and ones place values. Using tens and ones blocks will make math easy and fun for everyone!

Put your students to the test with this lesson that helps them learn the tens and ones places with a memory game and worksheet!

Let's better understand multiplication and division concepts! Use this lesson to help students understand inverse operations between multiplication and division.

Five, ten, fifteen... Help your students practice their multiplication skills by teaching them to skip count by fives. In this lesson, they will use dice to practice math!
