UNIT 6: REPRESENT DECIMALS TO HUNDREDTHS
UNIT 6: REPRESENT DECIMALS TO HUNDREDTHS
We will cover the following:
Represent Decimals to Hundredths
represent the value of the digit in whole numbers through 1,000,000,000 [999,999 in this unit] and decimals to the hundredths using expanded notation and numerals.
interpret the value of each place-value position as 10 times the position to the right and as one-tenth of the value of the place to its left.
represent decimals, including tenths and hundredths, using concrete and visual models and money.
Compare and Order Decimals
compare and order decimals using concrete and visual models to the hundredths.
Relate Fractions and Decimals
relate decimals to fractions that name tenths and hundredths.
determine the corresponding decimal to the tenths or hundredths place of a specified point on a number line.
represent fractions and decimals to the tenths or hundredths as distances from zero on a number line.
include measuring lengths to the nearest half, fourth, fifth, tenth, or hundredth of a unit, as appropriate
Add and Subtract Whole Numbers and Decimals
add and subtract whole numbers and decimals to the hundredths place using the standard algorithm.
Problem Solving (Some of the types of problems students should be solving during this unit)
solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate.
word problems using measurement contexts, focus on decimals in this unit, addition and subtraction only in this unit]
solve one- and two-step [addition and subtraction] problems using data in whole number, decimal, and fraction form in a frequency table, dot plot, or stem-and-leaf plot.
UNIT 7: APPLYING ALGEBRAIC REASONING AND COMPUTATION SKILLS TO MEASUREMENT
UNIT 7: APPLYING ALGEBRAIC REASONING AND COMPUTATION SKILLS TO MEASUREMENT
We will cover the following:
Input-Output Tables
represent problems using an input-output table and numerical expressions to generate a number pattern that follows a given rule representing the relationship of the values in the resulting sequence and their position in the sequence.
Measurement Conversions Using Tables
identify relative sizes of measurement units within the customary and metric systems.
convert measurements within the same measurement system, customary or metric, from a smaller unit into a larger unit or a larger unit into a smaller unit when given other equivalent measures represented in a table.
Perimeter and Area Formulas
solve problems related to perimeter and area of rectangles where dimensions are whole numbers.
use models to determine the formulas for the perimeter of a rectangle (l + w + l + w or 2l + 2w), including the special form for perimeter of a square (4s) and the area of a rectangle (l x w).
Represent and Solve Measurement Problems
solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate. There is a focus on elapsed time in this unit, word problems may include measurement conversions.
represent multi-step problems involving the four operations with whole numbers using strip diagrams and equations with a letter standing for the unknown quantity.
UNIT 8: DATA ANALYSIS
UNIT 8: DATA ANALYSIS
We will cover the following:
Data Analysis
represent data on a frequency table, dot plot, or stem-and-leaf plot marked with whole numbers and fractions.[focus on stem-and-leaf plots in this unit]
solve one- and two-step problems using data in whole number, decimal, and fraction form in a frequency table, dot plot, or stem-and-leaf plot.
UNIT 9: PERSONAL FINANCIAL LITERACY
UNIT 9: PERSONAL FINANCIAL LITERACY
Personal Financial Literacy
distinguish between fixed and variable expenses.
calculate profit in a given situation.
compare the advantages and disadvantages of various savings options.
describe how to allocate a weekly allowance among spending; saving, including for college; and sharing.
describe the basic purpose of financial institutions, including keeping money safe, borrowing money, and lending.

The goal of this unit is learning to read, write, represent, and compare 3-digit number. This requires students to extend the concept of unitizing Unitizing is challenging for young learners because it requires them to hold two ideas simultaneously - they must think of a quantity as one unit and as a collection of a different type of unit. In the case of hundreds, the unit is hundred, but there are two possible collections to consider, 100 ones and 10 tens. Despite the challenges, student developing this concept is critical to understanding the structure of our place value system which is built on the idea of continuously unitizing groups of 10 into tens (10 ones), hundreds (10 tens), thousands (10 hundreds), etc. (RRISD AARC)
