Plot 8, and 9, on the two outermost spots on the number line below. This task helps students understand the concept of rounding by using the number line to illustrate how to find the closest benchmark numbers. This task also helps students lay the groundwork for developing more efficient rules for rounding based on the digits in a given number. As students reason through the value of each tick mark on each number line, teachers should engage in formative assessment questioning to check that students understand what one tenth of each interval must be as the interval changes throughout this question.
It will be natural for students to try initial values that may be wrong for each increment, so when possible let them test out their own predictions and learn to correct their own misunderstandings. As they count up by that unit on their number line, they should realize their mistakes as they see the distance between each number on their number line will not be equal.
Grade 4. Domain Number and Operations in Base Ten. Cluster Generalize place value understanding for multi-digit whole numbers. A study was done of recent college graduates and found their mean value for their credit card accounts was dollars. The number line below shows this situation. How far apart are these values? We subtract the two numbers and recall that when we subtract two negative numbers when we are looking at the right minus the left, we make them positive and subtract the positive numbers.
In statistics, we are asked to find a z-score, which tells us how unusual an event is. The first step in finding a z-score is to calculate the distance a value is from the mean. The number line below depicts the mean of Find the distance between these two points.
Learning Outcomes Calculate the distance between two points on a number line when both are non-negative. Label the points where the line crosses the axes. Welcome to MathHomeworkAnswers.
