MEASUREMENT

Concept/Skill

1998 Core Curriculum

2005 Core Curriculum
Units of Measurement Grades Prekindergarten-7 (develop an understanding of both metric and customary units, beginning with non-standard units and progressing to standard units) Prekindergarten (informal)

Grades Kindergarten-1 (attributes of length, non-standard units)

Grade 1 (understand that length can be measured, introduce inch)

Grade 2 (standard (whole inches and whole feet) and non-standard units)

Grade 3 (whole and ½ inches, whole feet, and whole yards)

Grade 4 (whole, ½ and ¼ inches, whole feet, whole yards, whole centimeters, and whole meters, equivalent standard units of length)

Grade 5 (extend to inch, identify customary and metric units, measure to the nearest centimeter, identify equivalent customary and metric units of length, convert within a given system)

Grade 8 (dimensional analysis, including Celsius to Fahrenheit and vice versa)
Measurement Tools Grades 1-2 (ruler and balance scale)

Grades 3-4 (select appropriate measurement tools)

Grades 5-6 (protractor and thermometer)

 Grades 2, 4 (ruler)

Grades 3, 4 (select appropriate tools)

Grades 5 (protractor)

Grade 7 (scale, draw central angles in a given circle using a protractor, precision of measure)
Estimation Prekindergarten-Kindergarten through Grades 7-8 (estimation is continued throughout)

Grades 1-2 (understand that measurement is approximate, never exact)

 Grade 1 (select appropriate non-standard units)

Grades 2-3 (include standard units)

Grades 5-7 (personal references for customary and metric units of length, justify reasonableness of estimates)
Time Prekindergarten-Kindergarten (develop concept of time)

Grades 1-2 (translate time between analog and digital)

Prekindergarten (day, night)

Grades Kindergarten-1 (morning, noon, afternoon, evening)
Clock Time

(Analog and Digital)

 Grades 1-2 (to the half-hour, quarter, and minute)

Grades 3-4 (relate clock face to fractions of a circle, tell time to five-minutes one-minute, and one-second intervals)

Grades 7-8 (estimate elapsed time)

 Grade 1 (tell time to the hour using both analog and digital clocks)

Grade 2 (tell time to half-hour and five minutes)

Grade 3 (tell time to the nearest minute, relate clock to fractions)

Grade 4 (calculate elapsed time in hours and half hours, not crossing a.m./p.m.)

Grade 5 (calculate elapsed time in hours and minutes)
Calendar Grades 1-2 (measure time to the day, month, and year, using a calendar) Grade 1 (days of the week and months of the year)

Grade 4 (elapsed time, days and weeks)
Money Prekindergarten-Kindergarten (names of coins and bills)

Grades 1-2 (make change up to $1.00)

 Grade 1 (know vocabulary, recognize coins, ¢ notation, coin combinations up to 25 cents)

Grade 2 (extend to bills ($1, $5, $10, and $20), dollar notation as $, equivalent combinations to make one dollar)

Grade 3 (count currency using correct symbolism)

Grade 4 (make change)

Grade 7 (introduce exchange rate and convert between different currencies)

Mass Grades 1-2 (use balance scale to measure mass, introduce kilogram)

Grades 3-4 (select metric units for mass)

Grades 5-6 (judge reasonableness of mass measures, measure mass using standard and non-standard units)

 Grade 2 (informal)

Grade 3 (extend to ounces and pounds)

Grade 4 (select appropriate tools, use grams and kilograms to measure mass)

Grade 7 (convert within a given system, identify customary and metric units of mass)
Capacity Prekindergarten-Kindergarten (introduce concept)

Grades 5-6 (relate to volume)

Prekindergarten-kindergarten (introduce concept)

Grades 5-6 (relate to volume)

 Grade 3 (attribute that can be measured, compare capacities, measure using cups, pints, quarts, and gallons)

Grade 4 (extend to milliliters and liters)

Grade 6 (measure capacity and calculate volume of rectangular prisms, identify customary and metric units of capacity, identify equivalent customary and metric units, determine personal references)

Grade 7 (convert capacities within a given system)
Angle Measurement Grades 7-8 (introduce protractor as a tool to measure and drawn angles) Grade 5 (introduce protractor as a tool to measure and draw angles)

Grade 7 (draw central angles in a circle)
Scale Grades 5-6 (introduce use of a scale in relation to measurement, use maps and scale drawings to represent real objects or places) Grade 7 (scale on a map)
