WMD Hall of Fame complete

Thanks for your participation in World Math Day 2013! Certificates coming soon.

This semester we are beginning with learning about place value, number relations, and some basic facts.

Number – Place Value

Students are learning to:

  • record the numerals of 2-digit numbers into the Ones and Tens place
  • understand the value of numbers in the ‘One’s position
  • understand the value of numbers in the ‘Ten’s position (one lot of ten = ten ones)
  • count by tens to at least 100
  • use Base-10 blocks to show the value of 2-digit numbers
  • use Base-10 blocks to add on to 2-digit numbers
  • begin to understand the value of one hundred (one hundred = ten lots of ten)

Last semester we learned the following things…

Measurement – Time, Temperature and Money

Students have learned to:

  • tell time to the hour and half hour
  • draw the hands on a clock to represent the time
  • use a calendar to determine the date
  • use the terms cold, warm, and hot to describe the temperature
  • begin to read and record the temperature on a thermometer in degrees Celsius
  • recognize and count with 1, 2, 5, and 10 Baht coins
  • count money in various combinations and solve money problems

Here are examples of what we have learnt about money:

Pattern and Function

Students are beginning to do the following:

  • Create, extend and transfer complex patterns, including number patterns
  • Clearly explain thinking verbally and pictorially and begin to use written language

Students have started working on an early algebra concept that our Everyday Math Program refers to as Frames and Arrows. We will be revisiting this model later in the year. Many students are finding this a difficult concept to grasp. In Grade 1 we will be using repeated addition as an introduction to multiplication, and frames and arrows will help us with that also.

Number – Counting

By the end of Grade 1, I would expect your child to count aloud to 100 and perhaps beyond. Some children can do this already which is great! They are above my expectations for this time of year.

For most Grade 1 students now, I would expect them to count from 1 to around 30 with a few mistakes. Common mistakes are saying the number 16 as ‘sixty’, or skipping one or two numbers as they count. I expect most students will count accurately to 30 by the end of the first semester this year.

Number – Reading Numbers

Most students find it easier to count aloud by rote, than to look at a written number and read it. By the end of the year, I would expect students to read any 2-digit number accurately, and to begin reading 3-digit numbers.

For now, students should correctly recognize the numbers 0-10, and most numbers to 20. We will be working soon on the ‘teen’ numbers 11-19. This should clear up any confusion between a ‘teen’ number (thirteen, fourteen, fifteen…) which represents 10+ a number, as opposed to a ‘ty’ number (twenty, thirty, forty…) which represents groups of ten.

Number – Writing Numbers

This is the style that we teach the students to form their numbers:

They can write a four like this ‘4’ if they wish. But we prefer that students do not add lines to the top of a 1 or through a 7, as these numbers can get confused with 7 and 4. 🙂

I expect that most students should be able to write numbers 1-10 without help. It is common for students at this age to reverse some numbers. For numbers 11 and up, they are probably going to need to look at a number line or a 100’s grid to copy the number. They should be able to write numbers to 20 instantly by the end of the first semester, and many 2-digit numbers (without help) by the end of Grade 1.
