Add numbers with decimal values using standard algorithm

Lesson

Points Plus

We can add numbers that include decimals in just the same way as we would add whole numbers. We just need to line up the numbers according to their place value. All the same addition strategies apply. 

Examples

question 1

Evaluate: $1.32+7.44$1.32+7.44

Think: Where do these numbers fit in the place value table?

Do: $1.32+7.44=8.76$1.32+7.44=8.76

 

question 2

Evaluate: $12.68+2.035$12.68+2.035

Think: Where do the numbers fit in the place value table?

Do: $12.68+2.035=14.715$12.68+2.035=14.715

QUESTION 3

Evaluate $0.75+0.48$0.75+0.48

  1.   $\editable{}$   $\editable{}$  
    + 0 . 7 5
      0 . 4 8
      $\editable{}$ . $\editable{}$ $\editable{}$

QUESTION 4

Evaluate $0.29$0.29 + $0.96$0.96.

QUESTION 5

Evaluate $8+\frac{8}{10}+\frac{1}{100}+\frac{1}{1000}$8+810+1100+11000, expressing your answer as a decimal.
