Bubble Gum Trial!

We had a great day Wednesday downtown. Our class loved participating in the Old Courthouse's Bubble Gum Trial. Our jury found our defendant guilty - poor Ana! Here are some pics of court process in action.

Fun Math

Happy Fall!

Cool Temperatures, Cool Math!

Our class got really into problem solving using predicting and testing on Friday! Here are a few to practice at home. They start easy, then get more challenging. See how you do! 

Two numbers have a sum of 15. Their difference is 1. What are the two numbers?

Two numbers have the sum of 22. Their difference is 4. What are the two numbers?

Two numbers have the sum of 39. Their difference is 11. What are the two numbers?

And finally, apply the skill in  a work problem! 

Maria practiced the recorder for 40 minutes on Saturday. She practiced 10 minutes less in the afternoon than than in the morning. How many minutes did Maria practice in the morning? in the afternoon?

Here's a chart to help with an example for the first one:

How did you do? Tricky, but fun! It was awesome to see how much fun we had with learning this, and how they enjoyed thinking and exercising their brains! You can see how really knowing your math facts will help with this skill.  Bring your answers to these problems to school tomorrow for a special treat! Happy thinking!
