Unit of InstructionUsing multiplication and division strategies with larger numbers/Weathering and erosion
Standard(s) Taught

MAFS.4.OA.1.3

Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

MAFS.4.NBT.2.5 

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.

MAFS.4.NBT.2.6

Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

MAFS.4.MD.1.3

Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor. 

SC.4.E.6.4

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

Math

Students will:

  • solve multi-step word problems (up to 3 steps) that involve multiplication and/or division using strategies for this grade level (E.g., rectangular arrays, area models, properties of operations, etc.).

  • represent a multi-step word problem using equations involving a variable represented by a letter for the unknown number.

  • interpret remainders that result from multi-step word problems

  • assess the reasonableness of answers to multi-step word problems using estimation strategies and mental computation prior to calculation.

  • use manipulatives or drawings of rectangular arrays and/or array models to solve and explain multi-digit multiplication problems that extend to 4-digit by 1-digit or up to 2-digit by 2-digit.

    use manipulatives or drawings of rectangular arrays and/or area models to solve and explain division problems that involve the division of a multi-digit dividend (with up to four digits) by a one-digit divisor. 

    • apply the perimeter formula (P = 2l + 2w) in real world and mathematical situations.

    • apply the area formula (A = l × w) in real world and mathematical situations.

    • solve for missing dimensions of rectangles when provided with the perimeter and/or area.

    • solve problems involving area of a composite figure composed of rectangles.

Science

Students will:

  • observe and record evidence of physical weathering in nature (e.g., plant roots growing up through a sidewalk, cement cracking from weather 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).

  • explain pictorially and in words, the steps of the rock cycle.
