Ten Flashing Fireflies

In maths, we have been learning to solve addition and subtraction story problems using pictures and manipulatives and then an equation. We have learned that the word “equation” is another name for a sum or number sentence.

Yesterday, we read a book called “Ten Flashing Fireflies.”

The cards on the left are part-part whole cards. We look at the number on one side and we have to work out what the number is on the other side that makes up the whole number at the top.

First, we warmed up our brains by doing some subitising. Subitising is being able to see how many things there are in a small collection without counting by ones. We used some dot cards.

In the book the children catch fireflies and put them in a jar.

As Mrs Stewart read the story, Frazer moved the fireflies into the jar using the interactive whiteboard.

We discussed what equations we could write that represented the pages in the story.

We then had our own firefly story problems to solve.

We had problems for numbers within 20 and some up to 100 if we wanted a challenge. Most Superstars chose challenge questions!!

We used our think mats to solve the equations.

What a busy morning!
