Step up or step down to rounding. Using a vertical number line, the lesson shows pupils the significance of rounding up or rounding down. Teachers encourage scholars to write the number in unit form and decide which form helped the most...

Mathematicians need to know that not all numbers are rational. We approximate irrational number with rational numbers. That is why a calculator may be misleading. This task give learners an opportunity to see how rounding a number and...

Reinforce number sense with a collection of math lessons for kindergarteners through fifth graders. Young mathematicians take part in hands-on activities, learning games, and complete skills-based worksheets to enhance proficiency...

How can you complete a simulation when it is not practical to determine the probability of an event? Class members learn that in some situations, it is not feasible to find the probability of an event, but they can estimate it by running...

Estimate the proportion in a population using sampling. The 20th installment in a series of 25 introduces how to determine proportions of categorical data within a population. Groups take random samples from a bag of cubes to determine...

A six-question interactive tasks mathematicians to solve addition and subtraction problems using front-end estimation. Question types consist of multiple-choice and true or false. A set of wooden beams that can be measured using moveable...

Wonder how many pieces of candy a teacher can eat. Pupils watch a video of candy in a bowl as some candy is removed to be eaten and others are added. Learners devise questions about the situation along with estimated solutions. Scholars...

Time for more candy! Learners view a video of a candy bowl where some of the candy is removed and more placed back. Scholars come up with questions about the scenario to answer and request additional information from the teacher. At the...

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...

Via the concrete setting of estimating the population of the US, your algebra learners are introduced to a logistic growth model. Comparing and contrasting logistic, exponential, linear and quadratic models, to see which fits the data...

Youngsters count, classify, and estimate quantities using buttons after a read aloud of The Button Box by Margarette S. Reid. They discuss the difference between guessing and estimating. Based on an experiment, they predict the...

To gain insight into the many different types of habitats, individuals must first get to know their own. Here, scholars explore their school environment, draw a map, compare and contrast their surroundings to larger ones. They then...

Students 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. Students...

How can we estimate time? Have your young mathematicians make a clock. Then they compare and contrast types of clocks. They practice writing times in two different ways and make a book about telling time.

Hooray for chocolate chip cookies! Ask your mathematicians to triple a chocolate chip cookie recipe and then reduce the recipe by one-fourth. Your class may need two days to complete, tripling the recipe the first day and reducing the...

Third graders round numbers between 0 and 1000 to the nearest 10 and to the nearest 100.

Collaborative learners will see the geometric addition of functions by graphing the sum of two graphed curves on the same coordinate plane. This task then naturally flows into giving learners the algebraic representation of the curves...

An exercise in finding the approximate time that a name would be called at a graduation. Estimating time may be difficult for some of the class, so this resource would not be a good choice for learning this standard. It does end with a...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...

This is great go-to activity for those spring or fall days when the weather beckons your geometry class outside. Learners start with a small tree, devising strategies to accurately estimate the leaf count. They must then tackle the...

High schoolers analyze the influences on urban life in the early and late 19th century, different economic, cultural, and social characteristics of slavery after 1800, the rise of racial hostility, and the ending of the Atlantic slave...

Students arrange themselves into small groups. Each group chooses a distance to measure ( the distance between the slide and the swings, for instance). Person #1 walks the distance, counting the number of his or her steps. Persons 2...

To compare how the Spanish, French, and English approached the exploration of North America, class groups examine primary source documents and become experts on one of four explorers: Francisco Coronado, Robert LaSalle, Samuel de...

From catching stars developed by African pygmy tribes to chop stix pick-up or the Hanukkah dreidel, use this list of diverse multicultural activities to help your learners draw connections to unique cultures of the...
