Math lesson app for teaching irrational numbers. Video instruction, worked examples, guided practice, instructor notes.
For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for teaching irrational numbers, square roots and perfect squares, and comparing and estimating expressions with irrational numbers and square roots--all key concepts in 8th grade.
NEW 4.0 version includes new 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 lesson app also includes a new NOTES feature: helpful tips for students, self-explanation questions, further information, and even suggestions for extension or family involvement--for every question and example!
Instructors and/or students can turn on and use the new canvas feature in the app to write all over the screen--take notes, highlight key terms and ideas, show work, etc.
