IXL's seventh-grade lessons include 255 skills divided into 26 categories, covering nearly all of the grade's Common Core standards. As students reach seventh grade, the need for differentiated instruction is bound to grow. IXL's adaptive nature helps keep practice level. However, the skills here are presented in isolation from one another. Through your own instruction, you'll need to help your students make deeper connections between skills, guiding them toward a more holistic understanding of math.
Your students will benefit most here if they've already got a strong conceptual understanding of the concepts they're practicing. As such, use IXL for extra practice and homework – you'll be able to track students' data and usage. While IXL's reward system is better suited to younger students, you can use the data reports to help set learning goals; as you know your students best, build in some custom rewards that are more likely to motivate them. If using the site in class, assign specific topics to each student, either as review or as an extension activity. As you circulate, take note of where students may need some help; there are bound to be some teachable moments.Continue reading Show less
Key Standards Supported
Expressions And Equations
Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.
Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, a + 0.05a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05.”
Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.
Ratios And Proportional Relationships
Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour.
Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.
Statistics And Probability
Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations. For example, decide whether the words in a chapter of a seventh-grade science book are generally longer than the words in a chapter of a fourth-grade science book.
Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language (e.g., “rolling double sixes”), identify the outcomes in the sample space which compose the event.
Design and use a simulation to generate frequencies for compound events. For example, use random digits as a simulation tool to approximate the answer to the question: If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood?
The Number System
Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.
Solve real-world and mathematical problems involving the four operations with rational numbers.
