# Math: Applying Addition and Subtraction of Fractions to Data Analysis and Perimeter

### Suggested Time Frame: 20 Instructional Days

##### Focus TEKS

• 5.3K add and subtract positive rational numbers fluently [fractions and mixed numbers with like and/or unlike denominators in this unit]; – R RC2  [fluency is not the goal of this unit; fluency will be developed over the year]
• 5.3A estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division; – S RC2
• 5.3H represent and solve addition and subtraction of fractions with unequal denominators referring to the same whole using objects and pictorial models and properties of operations; – S RC2

Perimeter – Add and Subtract to Solve Problems

• 5.4H represent and solve problems related to perimeter and/or area and related to volume. – R RC3 [whole number and fraction measurements in this unit]
• 2.9D determine the length of an object to the nearest [whole or fraction of a] marked unit using rulers, yardsticks, meter sticks, or measuring tapes

Data Analysis – Add and Subtract to Solve Problems

• 5.9C solve one- and two-step problems using data from a frequency table, dot plot, bar graph, stem-and-leaf plot, or scatterplot. – R RC4 [problems involving addition and subtraction of whole numbers and fractions in this unit]
• 5.9A represent categorical data with bar graphs or frequency tables and numerical data, including data sets of measurements in fractions or decimals, with dot plots or stem-and-leaf plots; – S RC4
##### Numeracy TEKS

Building Fluency with Multiplication and Division Facts

• 3.4F recall facts [zeros, ones, sixes, nines, and last facts (3 × 3, 3 × 7, 7 × 3, and 7 × 7) in this unit] to multiply up to 10 by 10 with automaticity and recall the corresponding division facts;- S RC2 [Including the Use a Rule, Build Up, and Build Down Strategies for Multiplication; Including the Think Multiplication Strategy for Division]
• 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 [arrays representing zeros, ones, sixes, nines, and last facts (3 × 3, 3 × 7, 7 × 3, and 7 × 7) in this unit]; – S RC2
• 3.4E represent multiplication facts [zeros, ones, sixes, nines, and last facts (3 × 3, 3 × 7, 7 × 3, and 7 × 7) in this unit] 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
