Which shape is the same? Young geometers match a triangle, circle, rectangle, and square to their identical counterparts, connecting them with a line from left to right. Then, they do the same thing with a set of four circular shapes,...

Some of these may look congruent, but examine them closely. There are three sets of shapes here for scholars to analyze as they circle all the congruent figures. For each set, there are three congruent shapes which are oriented in...

Which of these shapes is congruent? Young geometers examine five familiar shapes: triangle, oval, rectangle, triangle, and circle. Each is followed by a set of shapes, of which one is congruent. They circle the congruent...

Can your kindergartners recognize shapes? What about when they are in different orientations? Youngsters study groups of shapes to determine which have the same shape and size. Two of the groups have triangles and ovals, and the other...

These abstract shapes are pointing in different directions and young scholars determine which ones are oriented the same way. For each of five starting shapes they examine a set of four identical figures pointing in various directions,...

Each of these addition equations involves two addends that are multiples of 10. Although there isn't any regrouping necessary, some of the sums are three-digit. The first 16 of these 28 equations are vertically oriented and the second 12...

Use this guided set of equations to help scholars add double-digit numbers with decimals. They examine two examples before trying these on their own, many of which require regrouping. All of these have decimals to the hundredths place....

Teach ratios of line segments using an interactive approach. Scholars examine a line segment in the shape of a log and use their knowledge of ratios to divide it into various partitions. As an introductory lesson, the segment has a...

If lines aren't parallel or perpendicular, then what are they? An interactive lets users rotate a line to change its orientation with respect to another line. It then indicates whether the lines are parallel, perpendicular, or...

Are there only three options: parallel, perpendicular, or intersecting? Scholars move a given line in an interactive to change its orientation with respect to another line. The interactive indicates whether the lines are parallel,...

Learners explore ellipses by changing the lengths and orientation of the major and minor axis. Using the interactive, they determine the equation of the ellipse and its eccentricity. Given an equation the scholars identify the center,...

Learners prepare their garden plot. In this gardening lesson, students use the Internet or book on plants to make sure the plants they have selected will be able to grow in their garden. The learners assess and mark out the garden...

These shapes are pointing all over the place. Learners examine rows of crazy shapes to find the one pointing in the same direction as the first in the row. Keep in mind, these aren't the shapes your mathematicians are used to. Because...

Pupils manage and retrieve numbers and letters that are logically sorted. In this logical information lesson, students do the flood game from the PBS website. Pupils answer questions about library books.

Explore shape attributes with young geometers as they sort nine shapes based on their corners. Scholars determine whether or not each shape has a square corner, drawing it in the appropriate space accordingly. They are encouraged to use...

Can your first graders identify a cone? What about a cube? Or a prism? Help them find the differences between these shapes with this instructional activity, which provides a word bank for three-dimensional shapes. For extra practice,...

In this horizontal parabola instructional activity, students draw the graph for the horizontal parabola given to them. Students complete 10 problems.

Students learn five songs to define and develop understanding of the attributes of two- and three-dimensional figures and the meaning of mathematical terms. They classify objects as either two- or three-dimensional, through the use of...

Second graders write a Math Moments journal.

Students discover early number concepts for numbers 1 through 5. In this number concepts instructional activity, students work in stations doing hands-on activities such as sorting colored blocks, stringing beads, and counting sticks....

Students listen to a story "My Crazy Dream" with an intent to identify shapes in ordinary objects. They raise their hands when they've heard an object whose shape they can identify. They discuss their findings.

Students use shape puppets to review geometry content. They take turns singing songs, reading students poems, reciting class bulletin board notes and choral poems. They prepare for their summative assessments through play and interview...

The Math Forum Student Center provides math news, notes, challenges, and much more. Dr. Math is here with the answers to students' math questions. There's a teachers' section, a research division, and a parents' part. This site also...

This site from Science U gives a good example of reflection of symmetry. It also gives some background information about reflection as well.
