This Mimio lesson (.ink file) follows the Eureka Math (and EngageNY Math) curriculum. If you do not have a Mimio, do not worry, we have also included a PDF of the slides. Just project them up on your white board, and there you have it!
Here, 1st grade students extend their learning of comparing direct lengths to the new learning of indirect comparison whereby the length of one object is used to compare the lengths of two other objects. The objective of this lesson is to answer compare with difference unknown problems about lengths of two different objects measured in centimeters. Included in this file are Fluency Practice, an Application Problem, the Concept Development, Problem Set, Student Debrief questions, and Exit Ticket. .
You will find that this lesson makes teaching easy! You can finally set aside your teaching manual. Discussion prompts are posted on Concept Development slides, as well as additional practice problems. Students will get ample opportunity to master skills as you go along. With pictures and moving objects, you will find they will stay engaged throughout the whole lesson.
