Math: Calculating how many items were donated each day was a big part of our project. Children proudly brought food and placed it on the carpet as they entered the room each morning. We would estimate how many items were in the collection before placing the objects into groups. Some days the children sorted the food by shape of container; other days it was the size or type of the contents. They worked cooperatively to count the items and then reported how many had been donated in our classroom at the beginning of circle.
The children were confident in their number sense and computation abilities. Number talks had been a major focus during our whole group discussions and the children were confident using tools (e.g., ten frames, hundreds charts) and strategies (e.g., counting by tens, working with ‘friendly numbers’) to solve difficult math problems.
Each day the children suggested a number of ways to conduct an accurate count of the items. At first they worked with friendly numbers, placing the items in groups of five and counting by fives to get a total. The next day they counted using groups of 10. With experience and confidence they suggested more advanced strategies such as counting by groups of 25 or using ‘unfriendly numbers’ such as 13 for a challenge.
When the time came to calculate the final number of items our ‘counting crew’ worked to group objects into collections of 25 and 100 and added everything together to get a sum of 967. Onlookers were astonished at the confidence and accuracy our kindergarten children demonstrated in this very challenging math problem. This authentic situation helped to differentiate the math experience for learners in a collaborative and meaningful way. Children created groupings of their own choice and these were added together; each child worked at his or her comfort level. It also demonstrated what children can accomplish when they are highly motivated, personally invested and challenged to independently solve a complex problem.
Literacy: There were also many opportunities for children to excel in literacy-based activities. Planned, purposeful writing and oral communication helped us successfully articulate our vision. Unlike more traditional writing practices (e.g., worksheets, journals), creating displays, posters and letters to the school community required the children to communicate in a more persuasive way as they tried to convince others to donate. The children had to consider their audience, purpose and voice, and focus on conveying their message in a clear and polished format.
We spent much time examining effective models of written and oral communication. We decided that it would be effective to write letters to all the teachers
