Number and Algebra/Additive Thinking
Learning Intention: To identify efficient problem-solving strategies
Learning experience overview
We have continued to explore different additive strategies that will assist us when approaching a problem that requires two or more numbers to be added.
Firstly, we discussed the different problem-solving strategies, as outlined on the poster, asking which ones would be most useful to them, considering the problem. We spoke about how the features of a calendar (days of the week) could be used to keep a track of the number of jellybeans each day.
For this activity students chose the strategy they felt worked best for them, and used it to solve the problem. We encouraged them to be as clear as possible when showing, not just the answer, but the way they reached that number.
Then they considered the second part of the problem, and what would change if the party was in 2 weeks time.
On the other side of the page are three Extending Prompts, where the number of new jellybeans each day, changed.
We discussed what it would mean to double each day and how we could set that out, to make it clear to see.
We asked them to reflect on their own learning, highlighting strategies used, ideas discovered and problems encountered.
Prompts/questions/responses
- What are the important words to remember when reading this problem? e.g. Friday/Saturday
- Would it help you to underline those words?
- What problem-solving strategies do you think will assist you?
- Does it help you to write down what you know, first?
- What helped you to work out your answer quickly?
- What do you already know, that can help you find the solution?
- Could you see any patterns?
- What was the name of the strategy that you used?
- How will you be able to check your answers?
What you can do now at home, to continue the learning from this experience
- Look for number patterns around you
- Create opportunities to add/subtract numbers of different values
- Use a calendar to note special events or occasions. Work out how many days/weeks until the event
- Choose a random number and count forwards by 10 - 23, 33, 43, 53, 63 – to 100 and beyond.
Then count backwards by 10 to the original number - Practise learning all the number pairs to 10 (9+1, 8+2. 7+3, 6 +4 etc) by heart
- Then try number pairs to 12, 20
- Practice doubling a specific number. Then try tripling it.
- When counting any number of items, count by 2’s or 5’s or 10’s rather than simply in 1’s
A.P.S. Choir
All Grade 2 students are welcome to join our choir.
Rehearsals are on Tuesday mornings at 8.15 a.m. in the Performing Arts Room.
We’d love to see you there.
