Learners examine a math worksheet and determine how to divide a single triangle into four of equal area. Using geometric principles, they sketch two additional ways to divide into into four equal triangles. To conclude, students...

Students locate lines of symmetry in regular polygons and predict the number of lines of symmetry in an octagon. In three different polygons, they construct all lines of symmetry and after making their prediction about the octagon,...

Sixth graders use number cubes to explore volume of two-dimensional shapes. They roll a die and construct a shape using the numbers rolled as measurements of the sides. They estimate the volume of a given object, and then use the...

Students draw diagrams demonstrating how it is possible to two central angles to be congruent and their minor arcs are not congruent. In groups, they illustrate theorems with their constructed circles, create diameters of circles that...

Students solve linear equations In this algebra activity, students create linear equations using integer coefficients greater than one. They graph their solution on a coordinate plane.

Tenth graders construct geometric figures using compasses and protractors.

Students build on what they know to make new discoveries. In this early childhood lesson plan, students engage in a block-building activity to develop language, math, and fine-motor skills.

Eighth graders investigate concepts related to fractions. This includes adding, subtracting, and reducing. There is a creative worksheet that has them creating their own ice cream sundaes using fractions.

Students make constructions and conjectures. In this geometry lesson, students construct right, acute and obtuse angles using a straight edge and a protractor. They investigate parallel lines and the angles formed by the angles.

In this math worksheet, students practice their skills in constructing reflections of shapes that are on a grid. This worksheet has 13 problems for the students to solve, and includes an answer sheet.

Third graders write out the multiplication facts of six; repeating them aloud. They then play a makeshift football game. They draw the field on construction paper and use figurines to represent players. They roll the dice to determine...

Students model and solve a real-world problem by constructing the centroid of a triangle. They explore relationships of the medians of a triangle and investigate how the centroid partitions each of the medians. Students investigate...

For this histograms worksheet, students construct 3 different histograms from the same data set. Students also sort the data and answer 1 discussion question.

Fourth graders compare two sets of data by using a double bar graph. In this data analysis lesson, 4th graders study a double bar graph and complete questions based upon the data. Students construct a table to show the data from the...

Sixth graders build figures out of tangrams. In this symmetry instructional activity, 6th graders view tangrams and identify the polygons included in them. Students divide into groups, identify their tangram pieces, define the lines of...

Students explore the degree, diameter, planarity, and size of graphs.  In this degree, diameter, planarity, and size of graphs lesson plan, students try to construct a graph with more than 12 vertices that satisfy all other...

Students identify triangles in the real world and construct their own triangle using drinking straws. They explore abstract triangles and find additional geometric shapes such as trapezoids. Students discuss similar shapes and examine...

How much sugar is in one bottle? Pupils use double number line diagrams to determine the amount of sugar in a 1L bottle of cola. The teacher leads a discussion on ways that double number lines can be of assistance in solving a...

How to use the relationship between multiplication and division to solve math word problems is the focus of the lesson presented here. In it, fourth graders work in groups to solve problems posed by the teacher. Then, each group is given...

Just because one integer is larger than another doesn't mean it will make sense right away. Go beyond note taking and show learners, through the use of algebra tiles and a Four-Pan Algebra Balance, how the numbers relate to one...

Who knew quilting would be so mathematical? Introduce linear equations and graphing while working with the lines of pre-designed quilts. Use the parts of the design to calculate the slope of the linear segments. The project...

What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Get a handle on equivalent fractions through the use of manipulatives. Using area models, sets, and length manipulatives like fraction strips and Cuisenaire rods, the class will gain a deeper understanding of equivalent fractions....

Solve story problems using fractions or decimals. Then, determine the reasonableness of answers using estimation.The detailed lesson plan includes essential questions, vocabulary, a materials list, and links to related units.
