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.
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|
• 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).
