Math (TAG): Measurement (Time Intervals, Weight, Capacity)

Suggested Time Frame: 11 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: 8 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: 3 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

Representing and Solving Story Problems (Suggested: 11 days)

  • Computation and Problem Solving
    • 3.4A solve with fluency one-step and two-step problems involving addition and subtraction within 1,000 using strategies based on place value, properties of operations, and the relationship between addition and subtraction; – R RC2
      • 3.4B round to the nearest 10 or 100 or use compatible numbers to estimate solutions to addition and subtraction problems; – S RC2
    • 3.4K solve one-step and two-step problems involving multiplication and division within 100 using strategies based on objects; pictorial models, including arrays, area models, and equal groups; properties of operations; or recall of facts. – R RC2
    • 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
  • Representing
    • 3.5A represent one- and two-step problems involving addition and subtraction of whole numbers to 1,000 using pictorial models, number lines, and equations; – R RC2
    • 3.5B represent and solve one- and two-step multiplication and division problems within 100 using arrays, strip diagrams, and equations; – R RC2
    • 3.5E represent real-world relationships using number pairs in a table and verbal descriptions. – R RC2
