Mental Maths

**You have all gotten so QUICK at adding big and small numbers in your head. Here’s a reminder of the tricks we learnt to get our brains busy!!**

**1. COUNT UP (best for adding on small numbers)**

**2. DOUBLES (we should know these off by heart)**

**3. NEAR DOUBLES**

12 + 13 = 25 (I know 12+12=24, so 12+13 is 1 one which is 25)

**4. TEN PARTNERS**

2+8=10

3+7=10

4+6=105+5=10

24 + 6 = 30 (I know this really quick because 6+4=10 plus 20 =30

**5. ADDING 10**

48+10=58

123+10=133

**6. SEE 9 THINK 10**

**7. SEE 11 THINK 10**

**8. ADDING 100**

44+100=144

188+100=288655+200=855

**9. SPLIT IT UP – GREAT FOR BIG NUMBERS**

126 + 40 + 4 +1 = 171

KEEP PRACTICING HERE….. A GREAT GAME
