Are they similar? The lesson provides an explanation of the angle-angle criterion for triangle similarity. Several problems allow the class to determine whether the two triangles with the given angle measures are similar or not. 

Before diving into operations with fractions, learners discover the foundation of fractions and how they interact with one another. Exactly as the title says, logic of fractions is the main goal of a resource that shows pupils how...

Put the graph into graphing and allow learners to understand the concept of point plotting and how it relates to data. The worksheet provides a nice way to connect data analysis to a graph and make predictions. The worksheets within...

Young mathematicians dive into the number line to discover decimals and how the numbers infinitely get smaller in between. They click the zoom button a few times and learn that the number line doesn't just stop at integers. Includes...

Discover an inverse variation pattern. A simple lesson plan design allows learners to explore a nonlinear pattern. Scholars analyze a distance, speed, and time relationship through tables and graphs. Eventually, they write an equation to...

Insects threaten the food production industry, and aphids are one of the big players! Analyzing data of aphid populations gives insight into their behaviors. Learners model the population data of an uninhibited population with an...

Controlling the efficiency of a greenhouse is a mathematical task. A collaborative project challenges learners to create an efficiency plan for a closed greenhouse. Using algebraic equations, they consider a set of constraints, design...

Take a look at linear functions in a new environment. A three-stage algebra project first asks learners to model the salt concentration of an aquarium using linear functions. Then, using iterations, pupils create a set of input-output...

Gain a little interest in functions with a real-life task. Young scholars analyze home loan data with a geometric sequence and series. They use the models to make predictions about the total loan payments at certain intervals in a...

So much can change in seven years. Young statisticians choose three types of businesses, such as toy stores and amusement parks, and use census data to determine how the number of those businesses in their state changed between 2010 to...

A lesson asks young mathematicians to investigate the social determinants and the environmental factors that influence risk factors associated with the spread of COVID-19. Class members then brainstorm what they can do to alleviate the...

Cha-ching! Using the practical resource, scholars investigate the different types of bank accounts and banking services available. Pupils view a PowerPoint, practice writing checks, and complete a checking account research project.

Become fluent in the language of mathematics. Scholars learn to divide multi-digit whole numbers and determine the most significant common factor and the least common multiple. They also investigate how to apply the distributive property...

Learners play a game requiring them to select groups of odd or even numbers of objects with the aim of reaching a total which is an odd number. They carry out a more formal investigation of patterns in additions of odd and even numbers.

Explore the world of shapes! After free tangram exploration and pair share time, learners describe various patterns and shapes in both the natural and designed world. They investigate the use of tangrams to create patterns and shapes.

Students will solve a word problem as an in depth investigation,. The lesson is based upon standards that are foundational to further development of math skills. The learners use logic and higher order thinking skills to accomplish the...

Sixth graders develop a rule for finding the volume of rectangular solids using colored cubes. They investigate the properties of solid figures and find the volume of an object by counting units. Students fill spaces with standard-sized...

Fifth graders investigate the symmetry of pattern block shapes. Students, working in groups determine whether each shape has line symmetry, rotational symmetry or both kinds of symmetry. Students determine how many lines of symmetry the...

Students get the opportunity to investigate the concept of data collecting. They explore how to tally and read a bar graph. Vocabulary about data is also be included. At the end of the lesson, individual students collect data independently.

Students investigate the farming business and occupations in agriculture. Basic multi-step math operations are performed in calculating some of the expenses involved in farming.

Fifth graders develop a questionnaire to investigate weather in different part of the US. They investigate how weather in one part of the country affects weather in another part. They predict the development of hurricanes.
