Connect division with multiplication through the use of models. Groups solve problems involving the division of a whole number by a fraction using models. The groups share their methods along with the corresponding division and...

Extend the place value system. The first lesson plan in a series of 18 extends the place value system to millions through thousandths. Using place value charts, pupils see how the value of a digit changes as it moves places. Teachers use...

Is there a way to connect creative thinking, logical reasoning, mathematical understanding, and humor? You bet there is! Kids begin by creating creative math quizzes, which require creative thinking to solve. For example, 1+1=24, one...

Get things cooking with the first lesson in this series on the science of food. Working in small groups, young scientists make and record observations about different mystery foods. These descriptions are then shared with the class and...

Reinforce concepts and encourage learner engagement with a collection of math games, science experiments, and cross curricular activities. In one fun resource, learners sort objects, keep a diary of everyday fractions, play a game using...

Introduces addition of decimals by using unit notation to represent the problem. Pupils use a place value chart to decompose the numbers and then add before connecting to the standard algorithm. 

If I want to build up my heart, where should I start? Science scholars use statistics in a sports physiology setting during an insightful experiment. Groups measure resting and active heart rates and develop a scatter plot that shows the...

If you think Dr. Seuss has no place in a math classroom, then take a look at this resource. Based on the classic children's book Green Eggs and Ham, this sequence of activities engages children learning to model real-world contexts...

Young scholars create a Road Trip. They work in small groups. Students are given a road map for each group. They plan a road trip between two cities on opposite edges of the map, estimating a reasonable distance to travel each day. Young...

Working on numbers 10 and 20? Don't forget your double ten frame! This double ten frame can also support addition and subtraction strategies and place value ideas. All on one page, ready to be printed and implemented as part of your math...

Piece by piece young scholars build a basic understanding of fractions in a Common Core-designed elementary math lesson plan. Through a series of hands-on activities and journaling exercises, and with the help...

Facilitate creativity in your math class as individuals learn the definition of a geometric reflection and correctly construct a model, as well as its reflected image. They use a perpendicular bisector and circles to elaborate on...

Working in small groups and in pairs, classmates build an understanding of what types of relationships can be used to model individual scatter plots. The nonlinear scatter plots in this lesson on relationships between two numerical...

Use the data for a good cause. Groups first analyze provided data and decide which function type would best model the situation. They then investigate a problem relevant to their lives by collecting data and analyzing the results using...

Humans have been developing number systems for thousands of years, and while they can be very different from one another, they can also share surprising similarities. Take your young mathematicians on a journey through the history...

Financial literacy is the way to teach! The class works in small groups to discover the relationship between education and income level. They use their math and problem-solving skills to complete two different activities. They work out a...

Have your class design their own mathematical study aids. Learners collaborate in groups on the design of tri-fold presentation describing the relationships between mathematical computations. Then, they write a business letter to the...

Class members come up with a hypothesis on the number of decimal digits in the product of two decimals. Learners work in groups to complete several decimal multiplication problems. The results help groups develop a conjecture on the...

Collect and analyze data to find out something interesting about classmates. Groups devise a statistical question and collect data from their group members. Individuals then create a display of their data and calculate descriptive...

Pupils work in pairs to investigate what it takes to prove that two triangles are similar. They work through various shortcuts to find which are enough to show a similarity relationship between the triangles. Small groups work with the...

Flip a coin to determine whether the probability of heads is one-half. Pupils use simulated data to find the experimental probability of flipping a coin. Participants compare the long run relative frequency with the known theoretical...

Sample pennies to gain an understanding of their ages. The 16th installment of a 25-part series requires groups to collect samples from a jar of pennies. Pupils compare the distribution of their samples with the distribution of the...

Polygons — it's all about the angles. Groups work with dynamic geometry software to find the sum of the measures of the angles of various polygons. After finding the information for several polygons, the groups generate a formula that...

Changing ratios make for interesting problems. Pupils solve problems that involve ratios between two quantities that change. Groups use tape diagrams to represent and solve classroom exercises and share their solutions.
