|Subject Area||Math and Science|
|Unit of Instruction||Multiplication/ Earth's Features|
– 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).
