I’m currently reading Why Before the HowSingapore Math Computation Strategies by Jana Hazkamp. I have been
trying to focus more on math lately since I’m always focused on reading
instruction. In my school district we use the Go Math (Common Core) textbook.
So, Jana Hazkamp’s book has help put a lot into perspective for me. Even as the
teacher I sometimes wonder why are they teaching the students to do it like
this? I like how Hazkamp starts off by
telling the readers how to use the book. She really wants you and your students
to get the full benefit of the knowledge shared in the book.
strategies discussed are regarding addition. She explains the benefit of using
number bonds in instruction and how decomposing numbers encourage students to
think about place value. Then, she moves on to subtraction. On page 41 she
introduces Place Value Disk. The disk are good for students who need to
physically manipulate the trading of tens for ones to support students
understanding of regrouping.
A few of my
students will regroup in an addition problem, but will not count the regrouped
ten. After reading how to use the Place Value Disk I was so excited. I ran to
Party City and bought a box of poker chips, then grabbed a magic marker and made
a set for my students. I cannot wait to try the chips in small group. Hazkamp
believes Place Value disk are a good manipulative to teach decomposing numbers
As I try the
different activities with my students in small group and centers I will let you
guys know what I think. If you want to join in reading a great book about math
instruction I recommend you get your hands on this book and join the me.
