I love to start a math lesson with a story. Iread one of my favourite books, **A Frog in the Bog by Karma Wilson** to a group of grade one and 2 students, then asked them to find out how many insects were in the frog’s stomach in all.

This grade 1 student recorded her thinking in numbers and words, drew dots above the digits and then counted the dots to find the total.

This child built a representation of the creatures using counters. Her arrangement clearly shows the growing pattern in the number of creatures the frog ate with each mouthful…

This child made sets to show the number of creatures, then counted to find the total. His counting system was really sophisticated. He found sets of fives on his page (1 and 4, 2 and 3, and 5) then counted them *5, 10, 1*5…. and did it all orally.

I was pleased to have been close enough to hear his solution, since no evidence of his developed number sense made it to the page – i have only this photo and that smug half grin to remind me of how clever he was. One reason I tote my digital camera about all the time…! 🙂
