#### Transcript of Singapore Math

Singapore Math at HTS
Language
Methods
Math in Focus
Making 10
10 is a very important number
Students practice making 10 and memorizing numbers to 10 in 1st Grade.
Will help with mental math as they go along.
Nearest 10
Students can add or subtract two digit numbers by making the next 10 and then subtracting or adding the appropriate number of ones.
Bar Modeling
Problem solving!
What is it?
Collaboration between educators from Singapore and from the US
Singapore methods begin in first grade.
Fewer topics - more focus on mastery
Why do we use this program?
Our program focuses on mental math!
Different leveled workbooks (reteach, on-level, enrichment)
Math Journals and 'Thinking Caps'
Number Bonds!
Our Objectives tonight:
To provide a better understanding of:
the language used
the methods used
3 + 2 = 5
2 + 3 = 5
5 - 2 = 3
5 - 3 = 2
Number Sentences
Concrete, Pictorial, and Abstract
Students learn Singapore Math in 3 formats:

equals
is the same as

6 + 4 = 9 + 1
Equal Sign
Example
7 + 5 =
Example
68 + 7 =
Example
28 + 26 =
adding and subtracting numbers based on their place value
Using Place Value (tens and ones)
Example
33 + 40 =
Example
24 + 5 =
Example
57 + 26 =
Example
37 + 26 =
Example
74 - 28 =
Also in 3+ digit numbers
578 - 98 =
Example
39 - 20 =
Example
48 - 4 =
Example
56 - 7 =

Jerry has found 21 perfect sea shells so far. Lindsey has found 16 more than Jerry. How many shells have they found in total?
Example
JKL Music Store sold 347 CDs last week, and 579 CDs this week. They now have 1294 CDs in the store. How many did they have to start?
