This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: What numbers can you make with 1, 2, 3, and 4? Using the operations of addition, subtraction, and multiplication, we can make many different numbers. F...

CK-12 Algebra Explorations is a hands-on series of activities that guides students from Pre-K to Grade 7 through algebraic concepts.

This grade 5 unit of algebra lessons explores diagrams and equations through 1 hands-on activity and 3 worksheets.

This short video and interactive assessment activity is designed to teach fourth graders about time and rate problems.

Students create four-legged walking robots and measure how far they travel across different types of surfaces. They design and create "shoes" to add to the robots' feet and observe the effect of their modifications on the net distance traveled across the various surface types. This activity illustrates how the specialized locomotive features of different species help them to survive or thrive in their habitat environments. The activity is best as an enrichment tool that follows a lesson that introduces the concept of biological adaptation to students.

This lesson is for Grades 4-5 math. At Home Learning Lessons are a partnership between the North Carolina Department of Public Instruction, PBS North Carolina, and the William and Ida Friday Institute for Educational Innovation. Each lesson contains a video instructional lesson, a PDF lesson plan with a transcript, and a PDF file of extension activities.  

The purpose of this game is to help students think flexibly about numbers and operations and to record multiple operations using proper notation.

This is a game that helps students develop flexibility with numbers and operations. Motivated to win the game, students begin developing mathematical generalizations that can be debriefed as a whole class after the activity.

Dancing Dash!
Create a dance for Dash to do along with students to demonstrate mastery of Math (addition/subtraction) and Science (motion/force).

Students play a game called "Clear the Board." Students use parentheses in order to make expressions equal a given total.

In this lesson, students play a game called "Clear the Board." Students use parentheses in order to make expressions equal a given total.

The purpose of this task is to generate a classroom discussion that helps students synthesize what they have learned about multiplication in previous grades.

Students quantify the percent of light reflected from solutions containing varying concentrations of red dye using LEGO© MINDSTORMS© NXT bricks and light sensors. They begin by analyzing a set of standard solutions with known concentrations of food coloring, and plot data to graphically determine the relationship between percent reflected light and dye concentration. Then they identify dye concentrations for two unknown solution samples based on how much light they reflect. Students gain an understanding of light scattering applications and how to determine properties of unknown samples based on a set of standard samples.

CK-12's Grade 4 Elementary Math is a series of videos and interactive videos designed to teach basic math concepts to 4th graders. Concepts covered include Addition and Subtraction, Multiplication and Division, Multiple Operations and Grouping, Place Value, Decimals, Time, Money, Measurement, and Geometry.

CK-12's Grade 5 Elementary Math is a series of videos and interactive videos designed to teach basic math concepts to 5th graders. Concepts covered include Multiplication and Division, Place Value, Multiple Operations and Grouping, Decimals, Time, Fractions, Money, Measurement, and Geometry.

Students apply their understanding of developing expressions and equations for a given context in order to determine the validity of equations. This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.

In this interactive game, students fill in the missing operations to make the mathematical expression true. Each game consists of 4 expressions. For each expression, the objective is to pick the correct operators as quickly as possible.
To choose an operator, simply click the appropriate symbol from the input panel. Operators must be entered from left to right, but calculations are done according to the correct order of operations. Incorrect answers are not accepted and a 15 second penalty is added to your time.

This short video and interactive assessment activity is designed to teach fourth graders about completing the number patterns based on the multiplication table.

In this lesson, students will apply their understanding of expressions to a real world problem involving travel distances.

In this lesson students evaluate expressions and consider how the Order of Operations changes the value of the expressions. 

This lesson strand is two in a series of two lessons that go through the steps of the Engineering and Design Process as needed for the construction of a prototype. The prototype is a musical instrument created through recycling landfill items. Based on the Landfill Harmonic from Paraguay, the motivation for the unit is GEDB: Music and Poverty- The Landfill Harmonic. The students in Paraguay (Latin America) live in a landfill and use the items to develop an orchestra. The unit clearly defines poverty and the resourcefulness that one must meet when living in a poverty culture. This prototype is the final product of a cross curricular, multicultural unit based on poverty and music with a direct connection to math, science, technology, engineering, arts, and multiple media skills. The links attached are created addressing the Landfill Harmonic. This lesson was developed by Christine Sisco as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

Students work as engineers and learn to conduct controlled experiments by changing one experimental variable at a time to study its effect on the experiment outcome. Specifically, they conduct experiments to determine the angular velocity for a gear train with varying gear ratios and lengths. Student groups assemble LEGO MINDSTORMS(TM) NXT robots with variously sized gears in a gear train and then design programs using the NXT software to cause the motor to rotate all the gears in the gear train. They use the LEGO data logging program and light sensors to set up experiments. They run the program with the motor and the light sensor at the same time and analyze the resulting plot in order to determine the angular velocity using the provided physics-based equations. Finally, students manipulate the gear train with different gears and different lengths in order to analyze all these factors and figure out which manipulation has a higher angular velocity. They use the equations for circumference of a circle and angular velocity; and convert units between radians and degrees.

This lesson allows students to explore and make sense conceptually of the order of operations. This is remixable if you provide additional supports for the range of learners.

This task allows students to explore and reason about how two multiplication equations compare to each other. This is remixable by adding student work or you can upload a new task aligned to the same standard.
