NSI
NSI (number sense intervention) makes an
enormous amount of sense to me. I have been very vocal about my dislike for our
current math curriculum (Envision). I don’t like the scope and sequence of the
program, nor do I like that the curriculum only allows for a one way strategy
to solve problems. Our current math curriculum concerning number sense goes
through numbers 0-10 focusing on one number a day. However, there is no building
on number relations for students to connect numbers and see patterns; instead
the numbers are taught exclusively and separately. The NSI uses a
visual/spatial technique to help students learn to count and develop
connections between numbers and counting. It also serves to help students understand
parts of a whole, as we introduce addition and subtraction. I think it is a
great idea to be nurturing number relationships while students are learning to
count and learning the basics about numbers. Why separate the two when they go
hand in hand?

Andrea,
ReplyDeleteAlthough I am not to familiar with Envision, I think that the text book at my school is very similar to what you are talking about. Giving students only one specific way to problem solve can hinder their growth. NSI seems like a great technique that should be taught and reinforced throughout all the grade levels. There are some many number connections that students can make and NSI seems to be a good way to combat those basic connections by giving students a meaningful learning experience.
