Math: Measurement (Time Intervals, Weight, Liquid Volume)

Suggested Time Frame: 13 Instructional Days


Focus TEKS

Time Intervals

  • 3.7C determine the solutions to problems involving addition and subtraction of time intervals in minutes using pictorial models or tools such as a 15-minute event plus a 30-minute event equals 45 minutes; – S RC3 [including relationships between minutes and hours]

Measuring Liquid Volume and Weight

  • 3.7E determine liquid volume (capacity) or weight using appropriate units and tools. – S RC3
    • 3.7D determine when it is appropriate to use measurements of liquid volume (capacity) or weight; – S RC3
    • 3.7A represent fractions of halves, fourths, and eighths as distances from zero on a number line; – S RC1 [recognizing the intervals on the scales of measurement tools]
Numeracy TEKS

Developing Strategies for Multiplying and Dividing within 100 (Suggested: 11 days)

  • 3.4F recall facts [all facts in this unit] to multiply up to 10 by 10 with automaticity and recall the corresponding division facts;- S RC2
    • 3.4D determine the total number of objects when equally-sized groups of objects are combined or arranged in arrays up to 10 by 10; – S RC2
    • 3.4E represent multiplication facts by using a variety of approaches such as repeated addition, equal-sized groups, arrays, area models, equal jumps on a number line, and skip counting; – S RC2
    • 3.4H determine the number of objects in each group when a set of objects is partitioned into equal shares or a set of objects is shared equally; – S RC2
  • 3.4G use strategies and algorithms, including the standard algorithm, to multiply a two-digit number by a one-digit number. Strategies may include mental math, partial products, and the commutative, associative, and distributive properties; – S RC2

Counting Patterns (Suggested: 2 days)

  • RRISD 3.3 skip count by fractions starting at 0 and describe patterns observed while counting [Skip count by thirds and sixths in this unit.]
Spiral Review TEKS

Revisiting Personal Financial Literacy (Suggested: 7 days)

  • 3.9 Personal financial literacy. The student applies mathematical process standards to manage one’s financial resources effectively for lifetime financial security. The student is expected to:
    • 3.9A explain the connection between human capital/labor and income; – S RC4
    • 3.9B describe the relationship between the availability or scarcity of resources and how that impacts cost; – S RC4
    • 3.9C identify the costs and benefits of planned and unplanned spending decisions; – NT
    • 3.9D explain that credit is used when wants or needs exceed the ability to pay and that it is the borrower’s responsibility to pay it back to the lender, usually with interest; – S RC4
    • 3.9E list reasons to save and explain the benefit of a savings plan, including for college; – S RC4
    • 3.9F identify decisions involving income, spending, saving, credit, and charitable giving. – NT

Summarizing and Analyzing Data (Suggested: 6 days)

  • 3.8A summarize a data set with multiple categories using a frequency table, dot plot, pictograph, or bar graph with scaled intervals; and – R RC4
    • 3.8B solve one- and two-step problems using categorical data represented with a frequency table, dot plot, pictograph, or bar graph with scaled intervals. – S RC4

Telling Time (Ongoing)

  • 2.9G read and write time to the nearest one-minute increment using analog and digital clocks and distinguish between a.m. and p.m.
