Objectives Covered:
NC.4.MD.1: Know relative sizes of measurement units. Solve problems involving metric measurement.
• Measure to solve problems involving metric units: centimeter, meter, gram, kilogram, Liter, milliliter.
• Add, subtract, multiply, and divide to solve one-step word problems involving whole-number measurements of length, mass, and capacity that are given in metric units.
NC.4.MD.2: Use multiplicative reasoning to convert metric measurements from a larger unit to a smaller unit using place value understanding, two-column tables, and length models
NC.4.NF.6: Use decimal notation to represent fractions. • Express, model and explain the equivalence between fractions with denominators of 10 and 100. • Use equivalent fractions to add two fractions with denominators of 10 or 100. • Represent tenths and hundredths with models, making connections between fractions and decimals
NC.4.NF.7: Compare two decimals to hundredths by reasoning about their size using area and length models, and recording the results of comparisons with the symbols >, =, or <. Recognize that comparisons are valid only when the two decimals refer to the same whole.
NC.4.MD.8: Solve word problems involving addition and subtraction of time intervals that cross the hour.
NC.4.OA.5: Generate and analyze a number or shape pattern that follows a given rule.

Some helpful tools:
The Metric System is a base 10 system; each unit of measure is 10x more (or less) than the one below (or above) it
Base Units:
Length-Meter
Weight/Mass-Gram
Capacity/Volume-Liter
Using the phrase "King Henry Doesn't Usually Drink Chocolate Milk" is a saying to remember the order of the prefixes of the Metric System
Using benchmarks for units is very helpful in making estimates. For example a meter is the length of your arms spread wide, the gram is the weight of a paperclip and a liter is the size of a large bottle of hand sanitizer.
You can convert between units by either moving a decimal to the left/right or multiplying/dividing by powers of 10

Some helpful tools:
Organize your time with a t-chart or a timeline to track elapsed time
Break down elapsed time into individual hours; 10 minutes; 5 minutes then 1 minute intervals to make counting easier

Some helpful tools:
Repeating Patterns: Follow a specific sequence; that sequence can be analyzed, described and applied
Growing Patters: These can be numbers or shapes; the amount gets larger for each term
Pattern Rules: A "rule" is applied to an amount (ex. add 3) then you get a new number. This can be done in a sequence of numbers or can be organized into a T-Chart
