In my teacher training they always taught us to try and make learning "real." Not to just teach the kids facts and information, but to make it relate to their real lives in a fun and meaningful way.
Fishing with Grandpa is the best. And doesn't every fisherman have a ruler to measure their prize fish? Of course! Not only did we count the number of fish we caught on the boat, we compared our numbers to the day before shore fishing, and measured each fish we caught. My little scientists insisted that we keep a record of each fish's length and type. Thankfully, Grandpa found a pen and paper for her!
On the boat we only caught 4 little sunfish. 2 were 5 inches and 2 were 6 inches. The day before, we caught 20 from shore in less than 30 minutes!
Now that is what I call some fun, real life numbers and measurement.
