This lesson is from Tools for NC Teachers. In this lesson, students apply their knowledge of place value to add whole numbers while exploring the standard algorithm. This is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students use digit cards to build a number based on a set of clues. Students will have the opportunity to create their own clues and work with partners to build numbers. This is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students will use base-ten blocks to build models of numbers including 10,000. The intention is to help students understand our base-ten place value system and explain that a digit in the ones place represents 10 times as much as it represents in the place to its right. This is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students apply their knowledge of place value to compare multi-digit whole numbers. This is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students will use various subtraction strategies to develop the standard subtraction algorithm. This lesson is intended to extend over several days to help students gain a deeper understanding of the algorithm and make connections between computation methods. This is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students solve a problem designed to help visualize the power of 10. The problem is set in the context of your local library and relates bookcases of books to our place value system. This is remixable.

In this lesson, students apply the concept of adding and subtracting whole numbers using the standard algorithms in order to buy items for the classroom.

This lesson is from Tools for NC Teachers. In this lesson, students will apply the concept of multiplicative comparisons by solving multiplication/division problems set within the context of the North Carolina Mountains. This is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students have the opportunity to apply their understanding of place value as they evaluate the lengths of North Carolina Rivers. This lesson focuses particularly on the understanding that “a digit in one place represents 10 times as much as it represents in the place to its right”. It is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students will play a game to generate and compare multi-digit numbers. Students will justify and explain their number comparisons based on their place value understanding. It is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students apply their knowledge of place value to subtract whole numbers using the standard algorithm.

In this lesson, students solve problems involving animal weights by subtracting and comparing multi-digit whole numbers.

This lesson is from Tools4NCTeachers. In this lesson, students use various strategies to solve division problems. This lesson is a good introductory lesson to dividing three-digit dividends by one-digit divisors. It allows the teacher to assess the strategies students use to solve division problems with larger numbers.

In this lesson, students apply concepts of doubling one factor and halving the other factor to solve multiplication problems. This is remixable.

This lesson is from Tools4NCTeachers. In this lesson, students make sense of and solve a contextual division problem. Students interpret remainders and solidify their understanding of terminology associated with division: divisor, dividend, quotient, and remainder. This is remixable.
