Students challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.

First graders practice place value by completing problems that allow them to group 10 items together to create groups of 10 and see what is left over. In this place value lesson plan, 1st graders use cups to put 10 items in them, and...

The Common Core is intended to help all children meet high academic standards. Here is a Common Core designed lesson that is intended for learners with communication or language difficulties. The lesson is written in a narrative style...

High schoolers discuss line graphs and scatter plots and the best situations in which to use them. Using the graphs, they determine the type of correlation between variables on a scatterplot. They create a scatterplot and line graph...

Twelve math lessons take kindergartners through the process of number sense and counting. The skills range from counting to ten, filling out ten frames, indicating ordinal position of an object, and counting by fives and tens to one...

The differences between tropical and temperate rainforests range from animals and flowers to climate and landscapes. Kindergarteners compare and contrast characteristics of their local forest to a tropical rainforest.

Scholars gain an insight into the relative size of planets and distance between inner and outer planets with the help of informational text, a data table, and a series of four questions.  

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

It won't take young mathematicians long to learn how to measure length with this fun, hands-on activity. Working in pairs, children use Unifix® or snap cubes to measure and record the lengths of different classroom objects. To extend the...

Through an engaging unit, chefs-in-training will sort and classify data using tally charts. Learners will also create bar graphs to display restaurant data and interpret data from bar graphs using a variety of categories....

Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson plan, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes....

Learners explore volume in relation to centimeter cubes and other nonstandard units of measurement using small containers. They will use hands-on materials to practice this concept. You will need small objects and containers to set this up.

Clay's as good a material as any to build a boat, right? An introductory lesson plan sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure...

students investigate the concept of using a ratio in the work of construction and solve problems using real life applications. They read descriptions of how various types of construction professionals use ratios on the job. The lesson...

Saturn's rings are made of dust, ice, and solid chunks of material. Individuals use spectrographs in this final installment of 22 lessons to determine the atmospheric elements. They analyze spectrums from Titan's atmosphere and...

Explore the influence of African-style masks on Western art. Learners create individual masks using construction paper. They discuss and explore the techniques used to create these types of masks. The resource includes links to...

Students explore the different methods used in celestial Navigation and astronavigation. In this math activity, students construct a sextant and demonstrate how it works.

Students look at how Greek classical art and philosophy influenced the French Revolution. In this French Revolution lesson, students use primary sources, Neoclassical art, to look at how they show what society was like during this time...

Students identify the title and author of stories. They create a database that supplies both graphic and written information to identify a book.

Young scholars identify and sort a variety of two- and three-dimensional objects and compare and contrast their attributes. They identify shapes, locate shapes on the faces of solids, sort real objects and explain the sorting rule, and...

Students assign numbers to describe objects. In this number lesson, students assign numbers to objects and compare more, less, and equal values. They write down descriptions of plants including the number of leaves and height of the...

Students discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Students sort objects and create patterns. In this sorting and graphing lesson, students work at centers to find a way to sort a group of objects, then make a graphical representation of the number of each item. Finally, students create...

Students discuss comparing the size of two different sets of blocks. They estimate the length of the long blocks by answering the following questions: How can you use the small blocks to find out?, and How many small blocks does it...
