STAAR STUDY GUIDE
Show work on all problems!!! Check work – remember the easiest problems need to be checked too!
Remember to underline, highlight, or circle key words in word problems that help you solve problems.
STAR problems that give you difficulty and be sure to look back over those problems later.
Line up decimals when adding and subtracting
Use stacking method for comparing decimals
Estimate before solving (rounding before you solve isn’t estimation), keep it easy on the brain
Remember rules for multiplying by 10,100, and 1,000 ex: 86 x 100 = 8,600 230 x 100 = 23,000
Parallel, Perpendicular, Acute, Right, Obtuse, Scalene, Isosoceles, Equilateral, Line of symmetry (turn your paper), Know attributes (Characteristics) of Polygons (Rhombus, Trapezoid, Hexagon, etc.) Trapezoid is the only quadrilateral that’s not a parallelogram. Know how to find the missing angle. Be able to tell if a number is 1/10 or 10 times another number.
Perimeter and Area (Formula Chart) – Perimeter is outside the figure =Fence & Area is inside the figure =Carpet (Area = Array)
Conversions (Use Mathematics Chart/ Gallon Guy/ Big G/T-Charts)
Know difference between weight and mass – use correct measurements
Look to see what the scale is counting by on graphs.
Look for key to see if something that equals 1 really equals 6 for graphs or measurement with a ruler.
Divisibility rules – don’t forget the rule for 3 (sum of digits is divisible by 3 then the entire # is divisible by 3)
Break a numberline up into fractions and decimals
>, =, or <
Understand meaning of BETWEEN, HALF, CONGRUENT, PRODUCT, PATTERNS, ANGLES, ABOUT, REASONABLE, ROUNDING
3 / 6 / 12 / 185 / 15 / 20 / ?
Be careful sometimes the pattern skips numbers and you have to consider those numbers. Make sure the rule works for all numbers in the pattern.
Use pictures to help you with fractions
