Patterns

An increasing pattern is a pattern that gets greater each time.

For example, the pattern 10, 15, 20, 25, 30 is an increasing pattern. It starts at 10 and increases by 5 each time.

decreasing pattern is a pattern that gets less each time.

For example, the pattern 18, 16, 14, 12, 10… is a decreasing pattern. It starts at 18 and decreases by 2 each time.

Numbers

Numbers can be represented in many ways.

We can use a numeral such as 368.

We can use a number word such as nine hundred twelve.

We can use base ten blocks.

                                           

We can use a place value chart.               

We can regroup to rename numbers by trading in ten smaller units for one larger unit, or one larger unit for ten smaller units.  (for example, 305 = 2 hundreds, 10 tens and 5 ones)

We can use number lines to represent and compare numbers.

We can use amounts we know to estimate other amounts.    

We can skip count by 2s, 3s, 4s, 5s, 10s, 25s, and 100s.
