# Q1 W8 Sept. 30th-Oct. 4th

Teacher Angela Mariner Math and Science 4 8 Multiplication/Rocks and Minerals
Standard(s) Taught

Math

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.

Science

SC.4E.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.

Learning Targets and Learning Criteria

Math

Students 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.

Science

Students will:

• 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).

Rocks and Minerals Vocab

1. Igneous- type of rock formed through the cooling and solidification of magma or lava. “fire formed”.
2. Sedimentary- type of rock formed by sediments pressed together in layers.
3. Metamorphic- type of rock that has changed forms due to heat and pressure.
4. Lava- hot molten erupted from a volcano.
5. Cleavage- when minerals split along their crystal shape.
6. Luster- the way minerals reflect light.
7. Streak- color left behind when the mineral is rubbed on an object.
8. Crystal- atoms that have bound together into an orderly three dimensional structure.
9. Mineral- crystals combining naturally into a solid.
10. Rock- mineral building blocks that have combined further by forces within the earth.
11. Fossil- the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.
