Eureka Math 4th Grade Module 4
Eureka Math is a free curriculum that can be found at engageny.org. I did not write this curriculum. I am selling my supplemental print outs that I have created for my classroom that go with the curriculum.
The application problems are like a "Do Now" or "Warm Up" problem. In the curriculum they do not have a student facing worksheet, so I have created them so scholars can do the work independently without having to copy from the board.
