Here’s two more subtraction strategies. When you would use these depends on the kind of numbers you find in the problems. Both are simple tricks you can use to subtract numbers more quickly in your head.
This is a simple strategy that’s good for “mental math.” Simply start with the smaller number, and count up until you reach the difference between the two numbers. Here’s a link to describe the strategy: Counting Up
Division four students discussed the details of this photo today. We tried to use what we observed to make informed inferences about the event shown. We aimed at supporting our observations with evidence from the photo.
Here’s your challenge: Use what you’ve learned about how to conduct advanced searches on Google. Do some investigating to see if you can find out more about this photo.
Students are now well under way planning and writing their speeches. There’s going to be some very engaging topics explored in division four’s speeches. Below you’ll find the first mini lesson on How to write effective introductions? You’ll also find the speech planner to help students organize their speech.
On our Lid pageyou’ll find out more about why we think Learning in Depth with our division 16 buddies is a great idea. We have been doing this for two afternoons and one morning over the last three weeks. The kids love it! On Day 3 we documented the questions we are curious about related to our topics. Students added ideas, facts and answers to our chart throughout the class.
They also showed evidence of their research and expanding knowledge by the conversations we heard, or discussions we engaged with student t0 student, or teachers with students. The grade four/fives are experienced and trained in how to do advanced web searching, how to distinguish poor web sources from helpful ones, and how to select useful information. So the K/ones had lots of expert help in finding out about their topics and writing or drawing what they are learning in their LiD journals. As teachers, we are providing ongoing guidance and feedback on the research process. Moving forward, we will scaffold the learning by helping students generate ideas of how they can share their learning with authentic audiences.
Here’s some of the things we heard when we listened for the learning today:
toothpaste is made of some very unhealthy materials – like bleach and sugar.
there is a legend that the Nazis buried three trains laden with gold and treasures somewhere in Poland
the world’s oldest map is from 600 BCE
30% of the world’s butterflies live in the Amazon rain forest
1/4 of all animals on the earth’s surface are beetles. Beetles provide far more calories and protein per pound than beef.
clothing in the Victorian era was very impractical
in the tundra biome there is only an average of 50 days in the summer
polar bears have to travel greater and greater distances for food because of polar ice melt caused by climate change
every state in the USA has its own tree
in Ancient civilizations, they became sophisticated once they discovered how to use metals
the biggest active volcano on earth is 2000 square miles
“I learned a lot from helping someone else learn about her topic!”
Div four did some impromptu 30 second practice speeches to start thinking from the audience’s perspective, about writing and creating powerful speeches. What should good speeches look like and sound like?
Use the feedback criteria and this form to make notes on each speech: PMI CHART
Which speech is the most effective?
What feedback would you provide for each? How could each speech be improved?
The kids suggested during our post-lunch discussion today that this should be our class motto! So, I borrowed someone else’s picture and changed it. Great topic for discussion with your kids about what success really looks like.
