This article describes the principle of Universal Design for Learning and how teachers can use this principle when designing lessons.

This resource is from Tools4NCTeachers.The goals of this lesson are to a) use objects or drawings to find the number that makes 10 when added to a known number, and b) record answers using drawings or expressions.Remix this lesson to share addtional problems, extension ideas, or student work samples.

This lesson is part of Tools4NCTeachers.In this lesson, students practice solving unknown-addend problems by using addition strategies or changing to subtraction problems. Task cards and extension actvities are included. 

This resource is from Tools4NCTeachers.In this lesson, students work with different quantities to determine if they have the same value / equal.  The information is presented in a context, not simply in an equation format, so students will need to apply their understanding of problem solving and resulting equations along with computation in order to determine if the amounts are equal.  Students will explain and defend their answers.  This file includes lesson, student recording sheets, and printable exit tickets.  Remix this lesson to include extension ideas or student work samples.

This resource is from Tools4NCTeachers.  This is a set of nine (9) tasks, which may be used for instruction or assessment. Each attachment contains a separate task, rubric, and student recording sheet. The word problems in these tasks involve 'adding to' or 'taking from' a quantity. In these specific problems, the change is unknown. For example:There were 17 ducks in the pond.  Some flew away, and now there are 8 ducks in the pond.  How many ducks flew away?Remix this resource to include student work samples or addtional tasks.

This resource is from Tools4NCTeachers.  This is a set of ten (10) tasks, which may be used for instruction or assessment.  Each file contains a separate task, rubric, and recording sheets.  The word problems in these tasks focus around making comparisons, where the difference between the two quantities is unknown.  For example, students may find the difference between two measurements or between the two sets of objects.Remix this resource to include extension ideas or addtional tasks.

This resource is from Tools4NCTeachers.  This task may be used for instruction or assessment.  It focuses around a put-together/take apart problem where one of the addends is unknown.  The file contains the task, rubric, and student recording sheet. Remix this resource to include student work samples or addtional tasks.

This resource is from Tools4NCTeachers. This file contains a set of 4 tasks (including scoring rubric and student recording sheet).  The tasks may be used for instruction or assessment.  Each focuses on solving a problem with an unknown addend.  Remix this resource to include student work samples or addtional tasks.

In this lesson, students "notice" and "wonder" as they look at a real world photograph. Then, they use a variety of representations to solve a problem related to the photo.

By the end of this lesson, students should be able to solve a
"put together, take apart" word problem by decomposing 8 in a variety of ways.

Gene expression and proteins will be covered in this activity.
Proteins are complex molecules made up of subunits called amino acids. There are 20 different amino acids and the different combinations of these is what makes one protein different from the next. There can be hundreds or thousands of individual amino acids in a protein. This amino acid sequence determines a protein’s structure and function.
