Friday 24 th April Make Arrays Starter Activity

Friday 24 th April: Make Arrays Starter Activity:

Yesterday we looked at arrays, here is one I made. Remember rows go across and columns go down. First I counted that there were 2 rows and there were 5 circles in each row. There are 2 rows and 5 columns. To find out how many circles I chose to count the columns so I counted in 2’s as there are 2 circles in each column. There are 10 circles altogether.

Look at this next example. First I counted that there were 3 columns and 5 sunshine in each column. There is 3 columns and 5 rows. To find out how many suns there are, I could choose to count the rows in 3’s or count the columns in 5’s. As we have already learnt how to count in 5’s, that’s what I chose. I counted the columns in 5’s, there are 15 sunshines. This is the same as 5+5+5=15

5 As you know how to count in 5’s, you can use this to find out how many windows there altogether. Look at my example, of counting the rows in 5’s How many windows are there altogether? 10 15 20 This also means that there are 5 columns.

Challenge 1: Answer the questions about this array. You can count both the columns and the rows. Are the answers the same? Challenge 2: Use your toys or objects around the house to make your own array, count the columns and rows. Can you find out how many altogether? How did you work it out?
