# Math: Summarizing and Analyzing Data Using a Variety of Old and New Data Displays

### Suggested Time Frame: 10 Instructional Days

##### Focus TEKS

Collect and Display Data

• 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

Solve Problems Using Data

• 3.4A solve with fluency one-step and two-step problems involving addition and subtraction within 1,000 [with 1- and 2-digit numbers only in this unit] using strategies based on place value, properties of operations, and the relationship between addition and subtraction; – R RC2
• 3.5A represent one- and two-step problems involving addition and subtraction of whole numbers to 1,000 [with 1- and 2-digit numbers only in this unit] using pictorial models, number lines, and equations; – 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
##### Computational Fluency TEKS

Grade 2 Add and Subtract with Two-Digit Numbers

• 2.4B add up to four two-digit numbers and subtract two-digit numbers using mental strategies and algorithms based on knowledge of place value and properties of operations

Grade 2 Skip Counting – Coins

• 2.5A determine the value of a collection of coins up to one dollar [Skip counting by twos and tens with pennies and dimes only in this unit]
• 2.5B use the cent symbol, dollar sign, and the decimal point to name the value of a collection of coins
##### Spiral Review TEKS

Grade 2 Place Value Concepts

• Representing Numbers up to 1,200
• 2.2B use standard, word, and expanded forms to represent numbers up to 1,200
• 2.2A use concrete and pictorial models to compose and decompose numbers up to 1,200 in more than one way as a sum of so many thousands, hundreds, tens, and ones
• 2.2E locate the position of a given whole number on an open number line
• 2.2F name the whole number that corresponds to a specific point on a number line
• 2.7B use an understanding of place value to determine the number that is 10 or 100 more or less than a given number up to 1,200
• Comparing Numbers up to 1,200
• 2.2D use place value to compare and order whole numbers up to 1,200 using comparative language, numbers, and symbols (>, <, or =)
• 2.2C generate a number that is greater than or less than a given whole number up to 1,200
