Day03

__**Grace & Courtesy: Remembering Our Ideas, and the Theme of Friendship**__ I've been trying to summarize our ideas on posters so we don't lose track of them. Any volunteers to help with this when you have a free minute? After reading notebooks, friendship seems to be an important **theme** in a lot of our work (including mine). Let's think about friends in our reading and writing today. What is something really important about friends?

__**Quick Read-Aloud for Fun: CDC?**__ Look at the pictures for clues.

__**Challenges: Be Friendly if Asked for Help**__ Here's a list of the activities and who was involved in each one yesterday. If you're not sure what to do, ask the group that worked on it last before you ask the teacher.

__**Science: The Path of the Sun and Moon**__ Volunteer to inventory our science kit. What do we have? Be on the lookout for clear skies so we can test our sundials. Start moon journals. Did anyone see the moon last night?

__**Writing: Focus on Friendship**__ As you write, think about the characters you're writing about, and who their friends are. Can you help your reader feel more connected to the characters by talking about how they help their friends, or how their friends help them? Conference questions: How did you get the idea for writing this? What is the most important thing you would want someone who reads this to know? Who do you think you might share this with?

__**Math: Conjectures, Facts, and Open Equations**__

__//Group Discussion: Proving our conjectures about properties//__ We said that 0 plus any number is the same number. It seems obvious, but can you explain why? We are going to practice **proving** what we claim constantly. That way, when people disagree, you'll already be used to explain their thinking to each other, so you can figure out whose ideas make sense. How about the rest of these properties? Let's have every group pick one that they will choose to prove. __Challenge__: Can you prove the conjecture about multiplying by 10 and appending a 0?

__//Group work: Turning expressions into easier equivalent expressions.//__ Someone pointed out you can change an addition expression by moving one from one number to the other, and the sum doesn't change. Is this **conjecture** true for all numbers? Let's see how we can make other number sentences easier, and if we can come up with any more conjectures. Be sure in your groups to write the name of the person that first states a conjecture. Can you prove its always true? Maybe blocks can help.

8 + 7 = " "+ 5 52 + 43 = 50 + " " 135 + 135 = 200 + 60 + " "
 * Fill in the open equations to make them true.**

4 x 6 = (2 x 6) + (" " x 6) " " x 8 = (5 x 8) + (1 x 8) 9 x 7 = (10 x 7) - (" " x 7)

15 - 9 = " "- 10 83 - 17 = " " - 20 532 - 93 = " " - 100

__//Individual work: Making homework//__ Addition (+), multiplication (x), and subtraction (-) are called operations. Division is also an operation. Make up two "open equation" problems for a partner to solve, and provide four multiple choice options. Just like we did on Monday, decide which one is trickier. Write it the problem, with the four answers on the board, and I'll type it up for homework.

Let's pay attention to see if this author tells us anything about the friends of the people in this story. Can brothers and sisters be friends? Look for evidence of the importance of friendship in your independent reading as well. At end of conference: How long do you think it will take you to finish this book? What do you think you might read when you finish this book?
