Mathematician of the Week

Our mathematician of the week is a superstar! You have tried so hard to answer your length word problems by yourself, you recognised which operation to complete and you could show clear working out. Fantastic! ๐Ÿ™‚

Arrays, arrays, arrays

In maths, we have been learning how to can use arrays to help us to complete multiplication questions and then we had to answer some really tricky word problems.

We can using arrays to explore numbers

Arrays are useful models for multiplication which can be used in a variety of ways, ranging from highly structured lessons to games and open investigations. An array is formed by arranging a set of objects into rows and columns. Each column must contain the same number of objects as the other columns, and each row must have the same number as the other rows.

The following array, consisting of four columns and three rows, could be used to represent the number sentence 3 x 4 = 12.

Three rows, four columns

We can build number facts

Arrays can be used for building multiplication facts in a meaningful way. Before drilling and memorising tables, children must understand how these facts are derived. For example, by progressively adding another column of three objects, children can build the three-times tables for themselves. This representation not only assists in understanding the process, but provides a visual image for children to draw upon as they begin to use and memorise the basic number facts.

How to continue the learning at home:

  • Practise counting with your child in steps of 2, 3, 5 and 10 so that they can become fluent.
  • Help your child to know their 2x, 5x and 10x tables off by heart.
  • Once your child is confident with these tables, start with the 3x and 4x tables.

Mathematician of the Week

Well done to our first Mathematician of the Week of 2017.

spring-1-week-1We have been learning about how to use arrays in maths this week to help us with our multiplication. You were so quick at answering the multiplication word problems and showing really clear working out with arrays to help you to find the answer. Well done! ๐Ÿ™‚
