# Hooray for Heuristics!

In life, we will encounter different problems and we will need to know different ways to respond and solve those problems. We can apply this same understanding to Mathetics. In Mathematics, we need to use different methods to respond to problems, and we call this Mathematical Heuristics.

This week, Year 5 have been digging deep into Multiplication. Not only do we need to know how to answer multiplication calculations properly, we also need to know why we are correct. In order to prove our answers, we created concrete representations and explained them.

Year 5 have been working hard on reasoning their answers clearly and they are improving every day. Well done Year 5!

Did creating concrete models help you? Why?

Did you prefer using Base 10 (Diences) or Place Value Counters? Why?

1. I can’t wait to learn more about this learning activity Year 5! I’m intrigued and will be coming to see you to find out more…

2. Miss Cotter, who enjoys teaching Year 5, set us challenges to use base 10 (dienes) to figure out multiplication problems.

3. Miss Cotter, who enjoyed teaching Year 5, set us challenges to use deans to figure out multiplication problems.

4. I have found this lesson very entertaining -and I mean really entertaining. We learnt the best (most practical) ways to solve problems.

5. This work, which was really challenging, helped me to do multiplication with difficult numbers.

6. Miss Cotter, who is a fabulous singer, set mind buzzing questions in maths.

On number day, which is a day of excitement, we solved mind blowing questions.

7. Miss Cotter, the Year 5 teacher, wanted Year 5 to explain how to use the grid method using base ten and counters.

8. Miss Cotter,who taught us maths, taught us how to use a type of huesrustics to find out questions to multiplication sums. Miss Cotter, who wanted her class to be smart , taught her class how to use Base ten and counters. Miss Cotter,who wanted her class to impress people, taught her class how to use pictoral grid method.

9. Miss Cotter, who is year 5’s teacher, wanted the class to use the grid method using base 10.

10. Year 5, who learnt how to solve maths problems using heuristics, can now work out any long multiplication using the methods Miss Cotter taught.

11. Year 5, keep your comments coming (with your secret parenthesis challenge).

Remember, relative clauses are different to parenthesis.
Relative clause example:
Year 5, who were very enthusiastic, completed their Maths challenges.

Relative clauses add extra information about the noun in the sentence and begin with a relative pronoun.

Parenthesis is when extra information is added to the sentence.
Parenthesis example:
Year 5 were studying different heuristics (they knew they needed to make lots of Mathematical links).

The sentence will still make sense without the parenthesis.

Good luck!

12. Year 5 can now work out any long multiplication (by using the heuristics that Miss Cotter taught them).
