# Q1 W6-W8 Sept. 18th-Oct. 5th

Teacher Angela Mariner Math and Science 4 6-8 Using multiplication and division strategies with larger numbers/Earth's Movement-Moon/Rocks and Minerals
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.

SC.4.E.5.4

Relate that the rotation of Earth (day and night) and apparent movements of the sun, moon, and stars are connected.

SC.4.E.5.2

Describe the changes in the observable shape of the moon over the course of about a month.

SC.4.E.6.2

Identify the physical properties of common earth-forming minerals, including hardness, color, luster, cleavage, and streak color, and recognize the role of minerals in the formation of rocks.

SC.4.E.6.1

Identify the three categories of rocks: igneous, (formed from molten rock); sedimentary (pieces of other rocks and fossilized organisms); and metamorphic (formed from heat and pressure).

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.

Science

Students will:

• recognize that the moon does not produce its own light; it reflects light from the sun.

• recognize that the moon revolves around (orbits) Earth in about 28 days as Earth revolves around (orbits) the sun.

• describe the changes (patterns) that occur to the observable shape of the moon over the course of about a month that have been recorded in a science notebook.

• predict the changes in the observable shape of the moon starting at any point in the cycle.

• sequence moon patterns.

• compare observable shapes of the moon.

• explain that the moon’s physical shape does not actually change.

• explain that Earth’s rotation on its axis causes the moon to appear as though it is moves across the sky in the day or night sky.

• identify the physical properties of common earth-forming minerals, including hardness, color, luster, cleavage, and streak color.

• Investigate and record the physical properties of minerals using technology and tools when appropriate (for hardness you may use a glass plate or other minerals; for streak color you may use a streak plate or unglazed tile).

• explain that investigations of minerals do not always follow the scientific method but do involve the use of observations and evidence.

• compare observations made by other classmates explaining any differences in data.

• compare minerals based on physical properties.

• explain the role of minerals (clay, quartz, feldspar, calcite, talc, pyrite, graphite, and mica) and their importance in rock formation (i.e.: 2 or more minerals make up a rock).

• use technology and tools to study and investigate samples of rocks.

• observe and identify examples for each of the three categories of rocks (igneous, sedimentary, and metamorphic).

• construct models for each of the three categories of rocks to include major details.

• differentiate between the three different categories of rocks based on how each is formed and/or their physical properties.
