# Quarter 1, Week 7: Sept. 24-28

Teacher Brooke Brackney Math/Science/Social Studies 4th Grade 7 Using Multiplication and Division Strategies with larger numbers (next 2 1/2 weeks)/Earth’s Movement--Moon/Civics and Government
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

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.N.1.1

Raise questions about the natural world, use appropriate reference materials that support understanding to obtain information (identifying the source), conduct both individual and team investigations through free exploration and systematic investigations, and generate appropriate explanations based on those explorations

SC.4.N.1.3

Explain that science does not always follow a rigidly defined method (“the scientific method”) but that science does involve the use of observations and empirical evidence.

SC.4.N.1.4

Attempt reasonable answers to scientific questions and cite evidence in support

SC.4.N.1.6

Keep records that describe observations made, carefully distinguishing actual observations from ideas and inferences about the observations.

SC.4.N.1.7

Recognize and explain that scientists base their explanations on evidence.

Learning Targets and Learning Criteria

MATH:

Determine if a given equation is true or false i.e., by comparing, composing, and/or decomposing numbers without solving.

Use a variety of strategies to justify why an equation is true or false without solving.

Interpret an unknown quantity without solving.

Use manipulatives or drawings of a model to solve multi-digit multiplication problems that extend to 2-digit by 2-digit or up to 4-digit by 1-digit.

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

Apply the area formula (A = lw) 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.

Explain how two or more numbers relate to each other within an equation.

Create a balanced equation by comparing two sides of an equation.

Determine the unknown value to create a balanced equation.

Solve multi-step word problems (i.e., up to 3 steps) that involve multiplication and/or division using various strategies.

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

Assess the reasonableness of answers to multi-step word problems using estimation strategies and mental computation.

Solve division of a multi-digit number by a one-digit number using a variety of strategies.

SCIENCE:

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

Investigate the processed of physical weathering (breaking down of rock) using a model

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

Discuss the cause/effect relationships for erosion and weathering

Provide examples of how physical weathering and the erosion processes change Earth’s surface

SOCIAL STUDIES:

Summarize ways citizens can influence government and public policy.

Identify community and state problems.

Describe how citizens, including children, can help solve community and state problems. Examples may include, but are not limited to, voting, petitioning, conservation, and recycling.
