Guest Post: Problem Solving With Mrs Morris

This is a guest post by Mrs Morris. Mrs Morris used to team teach with Miss Jordan. She is currently on family leave looking after her baby girl.

Today was planning day for the grade three and four teachers. While the teachers were busy getting ready for next term, the students rotated around different classrooms for some exciting lessons.

Mrs Morris took all the grade threes and fours for a forty minute problem solving lesson. The lesson was called “Plants” and was adapted from the NRICH site. 

Watch the presentation below to see how the problem unfolds.

The students did a fabulous job of using problem solving strategies. Many started with “guess, check and improve” and some students moved on to “working systematically”.

Here are some of the 4A and 4B mathematicians using counters and Venn diagrams to try to solve the problem.

Many students found six or more solutions with a small number of children finding 11 or 12 possible arrangements!

How many solutions to the plants problem can you find?
