Farmer Bob goes to see his animals. The animals are all mixed up in different areas. He sees 10 legs. Which animals might he see?
This is only one of many problems my students work on in their Farmer Bob problem solving packets.
These problem solving activities support the first grade Common Core State Standards for Mathematics. The problems were designed to allow students to apply what they are learning about numbers into a problem solving setting. These two packets are great for the latter part of first grade or into second grade.
In Farmer Bob’s Farm Packet #1, students solve problems related to how many animal legs there are. I chose cows, spiders, bees, and chickens so there would be animals with different numbers of legs. This allowed me to create problems where students can use their knowledge of structuring numbers such as five and some more, doubles, sums of ten, and the skills of counting by multiples as well as other skills they have been exploring all year in first grade.
In Farmer Bob’s Farm Packet #2, students solve problems related to how many legs and also how much money it would cost to buy the animals. I chose cows, pigs, chickens, ducks, and horses with a variety of prices attached to each animal. This allowed me to create problems where students can use their knowledge of structuring numbers I listed above as well as other skills. In both packets, some students were using multiplication to solve the problems.
I use these packets as activities for when students finish their math work. Some students finish each packet quickly in a matter of a day or two. Others may work on the packets for several or more days.
I print each packet separately and copy the pages back to back. I also staple it down the sides so it opens like a booklet. On Packet #1, I add an extra blank sheet at the end for students who may need more space for their work.
