# Feb 18: maths new unit

Dear Parents,

We will start a new mathematics unit this week: Repeating Patterns and Number Sequences.

There are three mathematical foci:

Linear relationship (describing and representing ratios)

Situations that look very different may have the same underlying constant ratio.

We will learn how different situations can have the same underlying relationship between quantities.

We will also learn to

• Describe the relationship between two quantities in a constant ratio situation
• Use tables to represent the ratio relationship between two quantities
• Find the value of one quantity in a constant ratio situation, given the value of the order

Using tables and graphs to represent change

Tables are introduced as a powerful representation to show how one quantity changes in relation to another. Organising data in a table can help us uncover a rule that governs that relationship.

Our focus points include:

• Describing the pattern in the numbers in a column and interpreting the pattern in terms of the situation the table represents
• Describing what is the same about the situations that look different but can be represented by the same table
• Using information in a table to determine the relationship between two quantities

Number sequences

Associating the counting numbers with the elements of a repeating pattern reveals important characteristics of the pattern and also provides an avenue into studying the number sequences themselves.

Using the counting numbers in this way gives us a language to talk about the pattern.

Much of the work on repeating patterns in this unit is focused on multiples of 2, 3, 4 and 5.

Our focus points include:

• Triangles are on the ‘counting by three’ numbers, or the multiples of three. To find the position of the next triangle, count on or add on three to the last triangle.
• The squares land on the numbers 1, 4, 7, 10 and so forth. Where will the next square be?

An important part of our work throughout the unit is to consider how and why different situations generate the same number sequence.

Thank you.

Dear Parents,

Thank you for coming to the Student led Conferences. I hope you enjoyed seeing your child progress! Here are some learning updates.

Maths

We learned how to sort data and put them in different categories using a Venn diagram. Each one of us also came up with a survey question and conducted a survey. We were challenged to think of meaningful categories by which to sort the data and we also learned that data have to be presented and understood in a way everyone can understand without taking too long.

We have also practiced reading, creating and describing data from a line plot, table and the representation of pictures and concrete materials. Data handling requires precision. We have been reminded to be careful when counting data and drawing neatly when creating a representation of our data. Also, we conducted some surveys visiting some other classes in different grades! Your children did a wonderful job and also reflected on the way they conducted the surveys and discussed what we can do to make it more efficient and accurate next time.

Writing

We have been reading and writing a lot of poems lately. We discovered that poets use poets’ eyes to describe an object in an unusual or different way. This makes their poem more interesting. We have learned some strategies to make poems look and sound more poem-like e.g., comparative language, creating moods, repetition, precise words, line breaks, white spaces. We have also learned how to choose a topic to write a good poem.

IPC

We inquired into how the world has changed physically and looked at how dinosaurs lived. Students are researching collaboratively about a particular dinosaur and putting their discoveries onto a shared Google Slide. Working together in group is not easy but everyone is enjoying the challenge! We also ‘excavated’ fossils carefully removing stones (removing chocolate chips from the remainder of the biscuits) to scaffold paleontologists’ work. Children enjoyed this a lot!
