Marvellous (mental) maths

 

This week in Maths and Numeracy we have been learning to sort and display information.

“We used Venn diagrams to sort our materials.  You have to put the things in the correct place in the circles. You put something in the middle if its both things”.  (S)

“In the photo above you put the wooden circle in the middle because it is wood and a circle”. (H)

In this photo, we were sorting out things in the box. If it was blue it went where the blue whiteboard was, and if it was plastic it went where the plastic whiteboard was and if it was blue and plastic it went in the middle.” (G and M)

 

“We also used tally marks to record our sorting.  Once you’d done the tally marks you put the number in the last box”. (E)

“To make tally marks, you do four lines down and then one across”. (R).

“”As part of our mental maths we played a game.  We all had calculations and we swapped numbers around. Then we had to try and find groups of 4. There were two adds and two takeways in each group of 4 like this 5+10 =15, 10 + 5 =15, 15-5=10 and 15-10”. (B, S and G)
