My students have been working very hard with me ever since they started their groups a few weeks ago. We have spent some time learning what Multiplication looks like as an array, using Animal Strips. I use this material as it is an excellent way for the students to see what the groups are made up of i.e. 9 is made up of 5 and 4, 8 is made up of 5 and 3 etc and it moves them away from counting in ones or skip counting and towards looking at groups of/sets of/lots of instead. While my students are still getting a grasp of their multiplication facts, using this materials enables them to break down the numbers into the Multiplication tables they do already know like 5 and 3 or 5 and 2 and 2 (4).
This leads them into learning the strategies of Place Value Partitioning (breaking up the tens and ones) and Rounding and Compensating (rounding to the nearest ten and then subtracting the groups you added in the beginning). As my students generally have some knowledge of written strategies like algorithms, we look at those as well, which I teach them can be another tool to check their answer with but it should be one of many ways they know how to solve a problem.
Below are some photos of my year 7 & 8's - Group 8 (Trinaye, Michaela, Katelyn, Aisea, Harrison & Jerome) working with these Animal Strips to develop their understanding of Multiplication and related strategies; followed by a problem solving session where they needed to extract what the questions were asking them and then use their knowledge of these strategies to solve each problem. They were able to demonstrate all three strategies and are becoming much better at identifying the maths question within all the 'words' of each problem.
These questions were taken from the Mathematics Assessment Resource Banks (ARBS) Copyright 2011 Ministry of Education, Wellington, New Zealand.
The first question for example is:
"Hohepa worked in a store for 16 hours a week for 7 weeks over Christmas. Show how to work out how many hours he worked over that time"
Ka pai tamariki ma! I am sure with the use of a variety of materials and the opportunity to share and discuss your thinking you are all developing a wide range of strategies to help you when problem solving! Keep up the great work.

ReplyDeletelol I couldn't focus on the numeracy aspect of this post . I was so interested in that couch from a previous post . I was wondering if Miss Breen had one at home.
However once I got back to reading about the work you were doing I was blown away, multiplication is such an important aspect of Numeracy . You all have been learning strategies from Miss Breen (a couple I didn't know shhh...) that will be very useful to you as you get ready to move to High School (do they still call them HIgh Schools?) .
Miss Breen is very clever and she puts in a lot of time into making Numeracy.
Well done everyone.
well done awsome guys
ReplyDeleteyou gus are so good at math i wish i was good at math.
