Students took a quick assessment check this morning - 6 questions about multiplication and division of whole numbers. Tomorrow, we are hoping to finish Neighborhood designs. We also introduced the idea of decimals today, took some notes about decimal place value, and completed a handful of problems requiring conversion between wholes, tenths and hundredths. There is no assigned homework tonight. Enjoy the beautiful weather!

Apologies for the lack of recent posts; things have been a little hectic! Today, students began working on their Neighborhoods. They've computed several components using multiplication skills, and are now trying to figure out how to scale those items. I also began meeting with small groups to touch base about some Mental Math skills. Tomorrow, we will be taking our first Mathematical Olympiad! Parents are welcome, but there won't be much to see, as students will be working independently on those problems for about a half hour. The rest of the time will be spent on two-digit/4-digit division practice, or Neighborhoods, depending on the time .Tonight's homework is a Pizzazz practice page, 1-digit/4-digit division.
We added 2 new strategies to our list for division (keep in mind that we are still working with 1-digit divisors and up to 4-digit dividends): long division (the traditional way most of us learned), and short division (only for those students who were really comfortable with long division). I'm uploading a youtube link to a quick lesson on Long Division in case that will help you to help your child at home: https://www.youtube.com/watch?v=LGqBQrUYua4. Tonight's homework is to complete the "Division" paper (4 problems). Students have been told to solve EACH division problem using 2 different methods, and then to check their answer by multiplying. Please help them as needed. We plan to move on to 2-digit by 4-digit tomorrow, so you'll want your child to be ready! :) Good luck!
We continued working on division strategies. Today, we spent time as a whole class with 2 strategies: Multiplying Up and Partial Quotients. Students practiced both strategies in small groups and independently. Tonight's homework is to complete p.34 (Dividing with One-Digit Divisors) using either strategy. We crossed out several problems. Students who are PROFICIENT with the 2 strategies are welcome to ALSO attempt any of the crossed-out problems as an extension. :)
We had an adventure today! We used small-group mini-lesson "Nath-casts" to introduce 3 different strategies for division. Students worked through 2 example problems, then worked in smaller pairings for practice. We'll need more, so tomorrow we plan to conduct live mini-lessons to review each of the strategies, before we move on to full independent practice. There is no division homework tonight. Complete the PoW sheet fully for tomorrow (the "burrows" problem).
Today we worked on our model Problem of the Week (the one about the prairie dogs and their burrows). We used a combined strategy mix of "Make it Simpler", with "Make an Organized List", "Draw a Picture" and "Look for a Pattern". Tonight's homework (due Wednesday) is to complete the PoW Template with an explanation. We also returned to estimation in division for a brief exercise and discussion.
Students are working their way through a multiplication assessment. We're looking for confirmation of an understanding of the concepts behind multiplication up to two-digit by two-digit factors. We've had a very short week, so there is no "vadercast" for this Friday. Enjoy your weekend!
We spent most of Thursday in the computer lab, working on First in Math. There is no homework for the evening.
Whew! Feels like we've been away forever! We returned to division today (after working on this week's Problem of the Week for a bit). We're beginning with estimation, and today we learned how to estimate using the multiplicative inverse. So, tonight you should see your child turning their division problems into multiplication problems with a variable, then solving for the variable using their Powers of Ten "tricks". Tonight's homework is to complete A-54 using multiplication equations with a variable.
