Unit of InstructionUsing multiplication strategies with larger numbers/Rocks and Minerals
Standard(s) Taught


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.


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).


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


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.


Students will:

• 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.

• explain, pictorially and in words, the different ways rocks are formed.

• describe how each category of rock is formed. o igneous – formed from molten rock o sedimentary – formed with other pieces of rock and fossilized organisms o metamorphic – formed from heat and pressure

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

• 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).
