Add decimals with the same number of decimal places using this reasoning and problem solving worksheet. Differentiated three ways and includes an answer sheet for easy marking.

Questions 1, 4 and 7 (Problem Solving)

Developing Calculate the highest amount, adding 2 numbers with same decimal places involving tenths and hundredths, from a choice of amounts. Minimal exchanges.

Expected Calculate the highest amount, adding 3 numbers with same decimal places involving ones, tenths and hundredths, from a choice of amounts. Some exchanges.

Greater Depth Calculate the highest amount, adding 4 numbers with same decimal places involving tens, ones, tenths and hundredths, from a choice of amounts. Multiple exchanges.

Questions 2, 5 and 8 (Problem Solving)

Developing Move across a number grid of 5x5, calculating the compound sum as you go. Numbers include tenths and hundredths and the aim is to create the lowest sum.

Expected Move across a number grid of 7x7, calculating the compound sum as you go. Numbers include ones, tenths and hundredths and the aim is to create the lowest sum.

Greater Depth Move across a number grid of 8x8, calculating the compound sum as you go. Numbers include tens, ones, tenths and hundredths and the aim is to create the lowest sum.

Questions 3, 6 and 9 (Reasoning)

Developing Consider 3 additions of numbers including tenths and hundredths. Order the calculations from easiest to hardest giving reasoning for the position of each.
