Today, I did a task in which I learnt how to substitute a variable (letter) for a constant (number).
First, I read this article in which I learnt about substitution, variables, constants, negative numbers and powers.
Second, I watched this algebraic problem video so that I get an idea of what I am going to do.
Third, I opened this example google drawings and saw how to use images as variables.
Fourth, I chose my variables which were two pokemons (Dragonite and Charizard).
Next, I added a black background, title, key, symbols, brackets and variables.
Then, I thought about the questions that I would be writing. The answer to the first question is 55. The answer to the second question is -15. The answer to the third question is 7.
Lastly, I embedded my google drawings on my blog post so that I can share my work.
I learnt that: A variable is a symbol or a letter for an unknown number in an equation. A constant is a value that doesn't change and is not a variable. Substitution is when constants (numbers) are replaced with variables (letters). A power of a number says how many times to use the number in a multiplication.
An interesting fact is that algebra was created in the 9th century by Muhammad ibn Musa al-Khwarizmi who was a Muslim mathematician.
I liked doing this Summer Learning Journey task because I got to learn more about algebra which I didn't know before.
Kia ora Sahil!
ReplyDeleteWhat a detailed blog post you have shared! I learnt so much from your summary of your learning today! Can you check that I worked through your Silly Algebra problems correctly?
1) (5 x 10) + 5 = 55
2) 10 - (5 x 5) = -15
3) 10 / 5 = 2 + 5 = 7
I also really like that you have taken the time to understand the meanings of the algebraic terms ( e.g., variable, constant) and that you are applying these correctly in your explanations!
Are you a bit of a Pokemon fan? Do you collect the cards?
Look forward to hearing from you.

Kia ora Naomi,
DeleteThank you for commenting on my blog post and the feedback too.
Yes, all your answers are correct! The first one was 55, second one was -15 and the third one was 7.
I am big fan of pokemon and I love collecting pokemon cards too.
I also like playing pokemon card games with my friends.

ReplyDeleteWow!! You have been doing some amazing learning. I’m glad you enjoyed this activity and got to learn some new algebra skills - that's what the Summer Learning Journey is all about!
Great work explaining the steps you took and the math terms clearly. Your fact about algebra history is also very interesting!
Thanks for testing my math brain out with your awesome algebra questions. I got the same answers as Naomi, hopefully we are correct!
I’m marking this as an outstanding blog post for your attention to detail and awesome learning.
