TeacherKathleen Manning
Subject AreaMath and Science
Grade Level4
Week #1
Unit of InstructionMultiplication/ Earth's Features
Standard(s) Taught


– Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations.

– Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.


– Describe the basic differences between physical WEATHERING (breaking down of rock by wind, water, ice, temperature change, and plants) and EROSION (movement of rock by gravity, wind, water, and ice).

Learning Targets and Learning Criteria

The student will:

– Use manipulatives or drawings of rectangular arrays and/or array models to solve and explain multi-digit multiplication problems

– Apply an understanding of rectangular arrays and area models to connect to the partial products strategy.

– Observe and record evidence of physical weathering in nature (e.g., plant roots growing up through a sidewalk, cement cracking from temperature changes).

– Describe causes of physical weathering occurs (wind, water, ice, temperature change, and plants).

– Investigate the processes of physical weathering (breaking down a rock) using a model.

– Observe and record evidence of erosion in a science notebook.

– Describe causes of erosion (gravity, wind, water, and ice).

– Investigate the processes of erosion (movement of rock) using a model.

– Discuss the cause/effect relationships for erosion and weathering.

– Provide examples of how physical weathering and the erosion processes change Earth’s surface (constructive and destructive).
