Estimation Skills

Investigate the world of unknown quantities with a creative set of five lessons that provides problem situations for varying grade levels. Each problem presents a scenario of fruit with different weights and a balance scale. Using the...

Plant growth experiments offer rich, cross-curricular learning opportunities that can really excite and engage young learners. In this series, children work in pairs planting, measuring, and comparing the height of bean plants in order...

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

For many young children it seems obvious that longer objects are heavier than shorter objects. This assumption is put to the test as the class investigates the relationship between length and weight in a whole-group activity. Using a...

Students participate in a lesson that has the intention of working on estimation skills. They use pumpkins to estimate the number of seeds are inside. They collect data for each pumpkin and compare it to the estimation. Students question...

Chart your way to an understanding of nanoscale. Using a Google map, learners estimate a radius around their location of 1,000 and 1,000,000 meters. Predicting what 1,000,000,000 meters would look like takes them off the charts!...

Students sort through numerous seeds to find similarities and differences. For this sorting and classifying lesson, students divide up different plant seeds based on their similarities and differences, while keeping record of their...

Students plant bean seeds, watch them grow, and measure them with non-standard objects. They describe the bean's growth in a journal and record the growth on a calendar.

Students measure the amount of surface tension using a balance scale after a classroom demonstration students diagram the appearance of several liquids and label them.

Students discover bar graphs. In this primary math lesson plan, students identify the parts of watermelon seeds and other seeds. Students learn the proper names and common names which refer to the parts of the seeds as they create a bar...
