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

### Suggested Time Frame: 14 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: 14 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
##### Spiral Review TEKS

Geometry, Area, and Perimeter (Suggested: 10 days)

• Geometry
• 3.6A classify and sort two- and three-dimensional figures, including cones, cylinders, spheres, triangular and rectangular prisms, and cubes, based on attributes using formal geometric language; – R RC3
• 3.6B use attributes to recognize rhombuses, parallelograms, trapezoids, rectangles, and squares as examples of quadrilaterals and draw examples of quadrilaterals that do not belong to any of these subcategories; – S RC3
• Measure Area
• 3.6C determine the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row; – R RC3
• 3.6D decompose composite figures formed by rectangles into non-overlapping rectangles to determine the area of the original figure using the additive property of area; and – S RC3
• Measure Perimeter
• 3.7B determine the perimeter of a polygon or a missing length when given perimeter and remaining side lengths in problems; – R RC3
• 2.9D determine the length of an object to the nearest marked unit using rulers, yardsticks, meter sticks, or measuring tapes

Summarizing and Analyzing Data (Suggested: 4 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.
