Students build sled kites. in this kite building lesson plan, students must read directions for kite building and enlarge the proportions of the given kite pattern. Students focus on the angles and line of symmetry in their kite. 

Shape shifters examine and experiment with pattern shapes.  In this geometry lesson, they work in groups to name and describe pattern block shapes, and they discover the combinations of shapes that can be placed inside a hexagon.

Learners investigate shapes and sizes by creating a riddle.  In this geometry instructional activity, students read one of two books and investigate facts about an object's size.  Learners write a riddle using the facts they...

Students solve problems dealing with points, lines and planes. In this geometry lesson, students differentiate between parallel lines and planes. They find the intersection of lines and planes.

Students identify the relationship between angles and arcs. In this geometry lesson, students rotate and move the circle around to create different arcs on the TI-Navigator. They differentiate between major and minor arcs.

Students write the equation of a circle. For this geometry lesson, students check the solution of a coordinate pair by evaluating them. They graph the circle given the equation and radius.

Young scholars calculate the area of different polygons. For this geometry lesson, students find the area of complex polygons. They solve word problems using rates and distances.

Pupils construct geometric figures using Cabri Jr. in this constructing geometric figures using Cabri Jr. lesson plan. They familiarize themselves with Cabri Jr. and construct segments and triangles. Your learners will use various tools...

Young scholars investigate the properties of quadrilaterals formed by angle bisectors of a given quadrilateral and quadrilaterals formed by the medians of quadrilaterals. This Cabri Jr. lesson provides opportunity for conjecture and...

Students investigate and perform reflections and symmetry. In this geometry lesson, students compare and contrast the relationship between reflections and symmetries.

Students estimate and compare grapefruit weights. For this weight measurement and literacy lesson, students listen to the story Nate's Big Hair and the Grapefruit in There, then estimate the weight of a grapefruit after holding it....

Students broaden their outlook on geometry in their everyday environment. They explore the properties of parallel lines and parallelograms and discover ways to prove the existence of parallel lines and discuss the concept of parallel lines.

Students study geometric shapes and practice naming them properly. In this geometry lesson, students work in groups to give definitions of the vocabulary to each other in their own words. Students also visit a lower grade and teach...

Students recognize the features of geometric shapes.  For this geometric shapes lesson, students listen to Captain Invincible and the Space Shapes. Students create solid figures with marshmallows and toothpicks.  Students...

Students identify tangents, chords and secants. In this geometry lesson, students graph circles and identify angles created by secant lines, tangent lines and chords.

Learners use web applet to create congruent triangles. For this geometry lesson, students differentiate between congruent and similar. They create shapes online and drag those shapes around to create visuals of triangles.

Students determine the distance between two points.  In this distance formula lesson, groups of students determine the distance between points in real life situations.  They calculate the distance from one point in the...
