Fourth grade uses a math program called Math Investigations. Occassionally, there will be a parent letter sent home regarding activities that you can try at home to support the learning in class as well as some information about the unit of study.
Families are welcome to borrow a Math Investigation Resource Book. Please try to reinforce the way each new concept is being taught in class, even if you think you know an easier way. These concepts scaffold each year.
Math problems are typically scored on a 3 point basis. When applicable- 1 point for writing the proper equation, 1 point for showing how he/she solved the math problem/explained their thinking and 1 point for solving the problem correctly.
