Counting Ø Counting-Saying or writing numbers down up wards and d own wards. Eg: <<Number line Eg: 3 -6 -9 -12 -15 -18 -21 -24 -27 -30 Eg: 0. 52 -0. 58 -0. 62 -0. 68 -0. 72 -0. 78 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 4

Addition Ø Addition-Putting one and another number to create a whole number. Eg: 0. 625 And 7. 893 Makes 8. 518 Eg: 789 and 362 makes 1151 Eg: $13. 2 and $6. 8 makes $20 Eg: 7/4 and 5/8 makes 2 3/8

Subtraction Ø Subtraction-Having one number taking it away from another number. Eg: 368 take away 269 makes 99 Eg: 799 699 100 Eg: -24. 6 take away -22. 2 makes -46. 8 Take away Makes

Multiplication Ø Multiplication- Groups of things together or in rows/arrays. **** Four groups of Four 100354 6 602124 10 cm P= 40 cm A=100 cm² 10 cm

Division Ø Sharing things between a certain amount of people or things evenly. Eg: 2 250 125 006 Eg: 120 720 Eg: ********** <Share Between 2 groups of 10. **********

Equivalent Things that are exactly the same like identical twins. Eg: Half = 2/4 Eg: 0. 5= Half Eg: 2/4 = Half Eg: Right Angle (90◦)

Angles Ø Angles- two lines that meet up to create a corner. Angles are measured with a protractor a semi circle or a full circle. Measuring an angle you always start from the 0 and end up from a number between 0 -180 <Right angle 90 Continue to next slide.

Angles, examples. Ø Angles are have their own name. Ø Next Slide for more definitions.

More definitions Ø Angles are used in life when you’re moving furniture into a house so you need to measure if it’s a right angle (90 ) or and acute angle(90 -0 ) Click Here for last slide Acute angle.

More examples. All triangles= 180 ^65 << 360 (revolution)

Strategies Ø The Habits Of Mind I use to do this work was applying past knowledge to new situations, striving for accuracy and thinking flexibly because I had to think of different ways to create a sum.
