We have been problem solving in Prep!
During our maths sessions we have been working on our problem solving skills and doing some Rich Assessment Tasks (RATS). Problem solving tasks are important activities because they require the students to use and develop mathematical thinking skills as well as helping them to develop mathematical language to talk about the concepts that they are learning about. In Prep we also aim to use problem solving tasks as a way to help the students understand that Maths is a process rather than one correct answer.
Over the last couple of weeks we have been doing some problem solving with shapes.
This was one of the questions we posed to the students.
“I have some shapes on the back of my Geoboard. There are 11 sides and 11 corners altogether. What shapes might I have made”?
Here are some examples of what the students came up with in Prep B.
Some things we discovered were:
– Squares and rectangles have the same amount of sides and corners.
– It doesn’t take that many shapes to equal 11 sides and 11 corners.
– Just because a shape is ‘big’ does not mean that it has more sides or corners.
Another activity involved the shape pattern blocks and this question:
“How many ways can you fill this triangle”?
This required the students to use a variety of mathematical thinking skills such as measurement, shape and counting. They were given a variety of pattern blocks (even ones that wouldn’t fit) and were asked to see if they could make the triangle. Letting the students experiment and find multiple ways helps to increase their knowledge and understanding of shape and measurement which they will build onto, as well as pushing them to really think!
Here is what some of them came up with!
