StandardSolve problems involving measurement and conversion of measurements from a larger unit to a smaller unit
|
Core StandardMD4.1 Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ... MD4.2 Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

In Other WordsStudent is able to change units of measurement from one to another such as feet to inches, kilometers to meters, pounds to ounces, and hours to minutes. Student is also able to do problems relating to elapsed time (how much time has passed). Students are allowed to use this reference sheet on end of year testing.
|
If MasteredIf your child has mastered this concept, ask your child measurement questions in real world settings. For example, while making dinner if you need 2 cups of water ask your child how many ounces of water you'll need. Another example is to ask your child what time he/she should wake up if it takes him/her 25 minutes to get ready, 15 minutes to eat breakfast and 2 minutes to brush his/her teeth if he/she needs to be to school at 8:30. These real world applications are wonderful when checking for understanding. This StudyJams website also helps review elapsed time and has a few quiz questions at the end.
|
If Not Yet MasteredIf your child has not mastered this concept, ask your child measurement questions every day. While memorizing the conversions is nice, real world applications are best for gaining an understanding since your child will be able to use a reference sheet on the end of year test, which has the basic conversions. For example, while making dinner if you need 2 cups of water ask your child how many ounces of water you'll need. Another example is to ask your child what time he/she should wake up if it takes him/her 25 minutes to get ready, 15 minutes to eat breakfast and 2 minutes to brush his/her teeth if he/she needs to be to school at 8:30.
This YouTube video show customary conversions. This second YouTube video shows how to convert in metric units of measurement. Finally, the StudyJams website will go over elapsed time step by step and have questions to quiz yourself. |
StandardRepresent and interpret data using line plots
|
Core StandardMD.4. Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots. For example, from a line plot find and interpret the difference in length between the longest and shortest specimens in an insect collection.
|
In Other WordsA line plot is a graph with a number line across the bottom and X's to show amounts in each column. Students will make and describe line plots that may have fractions included in the number line.
|
If MasteredHave your child find objects to measure and then plot their lengths on a line plot. Small items will give your child experience with fractions.
|
If Not Yet MasteredSee textbook lesson 17-04. Find a collection of items of different lengths around the house, measure them and plot their lengths on a line plot. Refer to this online tutorial from k5learning.com for line plots

StandardDemonstrate understanding of concepts of angles
|
Core StandardMD.5. Geometric measurement: understand concepts of angle and measure angles. Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement: a. An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles. b. An angle that turns through n one-degree angles is said to have an angle measure of n degrees.
|
In Other WordsTell that an angle is made when two rays (part of a line that has one endpoint and goes on forever in one direction) share the same endpoint. Explain that angles are measures in degrees and that degrees relate to the outside of a circle.
|
If MasteredThere are many interactive games available at the following JMathPage website that will help your student see the real life applications of angles.
|
If Not Yet MasteredFirst, review what an angle is with your child using the AMathsDictionary. Click on "angles" from this site for a definition.
Next, take your child through the information found at MathIsFun.com After reviewing this information, proceed to apply the knowledge in the game "Measuring Angles with a Protractor" |
StandardDetermine perimeter and area of rectangles
|
Core StandardMD.3. Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
|
In Other WordsTell what the area (amount inside) of a rectangle is and how to figure it. Tell what the perimeter (distance around the outside) of a rectangle is and how to figure it.

StandardMeasure and sketch angles using a protractor
|
Core StandardMD.6. Geometric measurement: understand concepts of angle and measure angles. Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
|
In Other WordsUse a protractor (click here for printable version) to measure an angle, or draw an angle given a measurement.
|
If MasteredUse a protractor to measure angles around the house. Online interactive for additional practice is available at MathIsFun.com
