# Q1W9 (10/11 – 10/15)

Teacher Kathleen Manning Math and Science 4 9 Multiplication/ Earth's Features
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.4.E.6.2

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

– Recognize the role of minerals in the formation of rocks.

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.

– 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).
