The OpenSciEd elementary science program aligns with all NGSS standards for elementary education.
In this unit, students are introduced to numbers from 1,000 to 1,000,000 using a variety of models and operations. They will apply their previous understanding of place value and extend their learning of the relative size of numbers in each place up to one million.
The Teacher Guide is designed to provide background information on the mathematics being taught in this unit, the learning env
EARTH & SPACE SCIENCE-This module continues students' investigations of earth materials--soils, rocks, and water--that began in Level 1. In this module, students build on their understanding of the properties of soil, rocks, and water by investigating changes on the surface of Earth due to weathering and erosion. They learn about land forms and how those land forms change over time because of the interactions among soil, rocks, water, and wind. Students construct and use stream tables to investigate the flow of water over Earth's surfa
