I got this lesson from Kim Adsit's Spring math and literacy unit. We used flower masks to act out story subtraction problems. We did this several times to make sure everyone had a turn. While acting the story problems out, I made sure to talk about how we can not subtract more than we have and why that is so. We also orally said and wrote each equation as we acted it out. After acting out different stories I made up using flowers, the students made their own flower story. I used the sheet from Kim's unit, but I removed the lines, so that the students could use the space to draw a picture. They each thought of a story. Then then drew 5 flowers. Next, they put an "X" on the flowers that they wanted to take away and finished the equation at the top of the page. When everyone was finished, we partner shared the stories they made up. Then I chose a few students to share with the whole class. You will have to model how to share their story several times before the partner share in order to get them to tell the story in a narrative form.
