Math lesson app for adding and subtracting integers. Video instruction, worked examples, guided practice, and instructor notes.
For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for teaching about adding and subtracting negative numbers, in the context of practice, equations, and real-world contexts--a key concept in 7th grade.
NEW 5.0 version includes the popular Practice Meter feature, which can keep track of each student's practice level for this app across sessions. The purpose of the Practice Meter is to motivate students to come back and revisit this content and complete modules at regular intervals. Revisit the lesson app to keep your Practice Meter out of the red (or in the blue). It becomes easier over time to maintain your practice level above the key levels of 80 or 25, because the meter depletes much more slowly after a week, then a month, then 3 months, has passed.
This math lesson app also includes a NOTES feature: helpful tips for students, self-explanation questions, further information, and even suggestions for extension or family involvement--for every question and example!
Guzinta Math: Add and Subtract Negative Numbers focuses on practice with integer addition and subtraction, including solving word problems by applying addition and subtraction of negative numbers. Students use an interactive tool to model subtraction and addition with positive and negative numbers.
For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for teaching about adding and subtracting negative numbers--a key concept in 7th grade. The app includes detailed instructor notes for each guided practice problem, with notes about extending discussion around each worked example and problem.
This lesson includes an interactive number line tool, demonstrating the Slingshot Method of adding and subtracting with negative numbers. Students can use the tool to calculate integer sums and difference, but more importantly they can use the tool to gain fluency in thinking about how adding and subtracting negatives work on the number line--adding a negative "slingshots" you to the left of your starting point, and subtracting a negative "slingshots" you to the right.
Instructors and/or students can turn on and use the new canvas feature (with improved writing functionality) in the app to write all over the screen--take notes, highlight key terms and ideas, show work, etc.
