Stretagies for maths!!!!!

PLACE VALUE:123+65=...... 123+65=? you would go 123+60=183 then you go 183+5=188. To get the answer but you can also do by adding hundred then tens then ones like this. 100+0=100 20+60=80 then 3+5=8. then last step is to add all of it together like 100+80+8=188.(used for addition and subtrction problems only.)

ROUNDING AND COMPENSATING:96+54=...... 96+54? you go like this 96+4=100 then 54-4=50 then after that you go 100+50=150. because what ever you add on that side u do the oppersite to the other side. It's confusing at first but then you get use to it.(Used for addition problems only.)

EQUAL ADJUSTMENT:96-96=....96-47=?you would go96+4=100 then 47+4=51 when have done you go 100-51=49 because you always do the same number to both sides thats why its called equal adjustment. (Used for subtraction problems only).

NUMBER LINE:81-47=.....47+?=81you draw a line then write 47 by the left hand then 81 on the right hand the u do tide numbers like 47+10=57, 57+10=67,then 67+10=77 then 77+4=81 then add 10+10+10+4=34 so 47+34=81.(Used for subtraction problems only).

PARTIONING: 20+43..... 20+43=? you could go 20+?=40 wich is 20 then you could go add 3which equals 23. But you do it in your head just like that.(Used only for addition problems only).

AND LOTS MORE I WILL BE PUTTING MORE ON!!!!! THANKZ
