One more than correct answer  may be using a counting all strategy and miscounting

c)

12 [7 + 5]

Only adds two of the three numbers

Next steps:
First, check that students have read the question carefully.
If necessary, have students work in pairs, reading the question together and recording how to solve the problem by using materials, symbols, images or a number sentence.
Students can practise this skill with a range of word problems without needing to solve them.
Alternatively, read out a word problem and students hold up the correct operator (+, – initially, moving on to x and ÷ as appropriate).

Students may need to have access to materials such as number strips, counters, beans, plastic animals etc and be encouraged to count onetoone to confirm calculations.
Students can play board games where two, or more, dice are rolled and added together in order to work out how far to move a playing piece or counter on the board.

Only adds two of the three numbers
Students may need more practice with problems involving more than 2 numbers. Students could roll three dice and add all the numbers together.
Have students work in groups of three  each student puts a number of counters or a written number (09) in front of them and the group works out the total they have altogether. Share findings and strategies with other groups.
Develop understanding of the key idea Numbers can be rearranged and combined to make ten by exploring 'Make ten' (page 40 in the Numeracy Professional Development Projects Book 5: Teaching Addition, Subtraction, and Place Value).
Making Number Sentences is a Level 2 resource that could be used with individuals, groups or the whole class to practise this skill. For further extension or ideas, Making Number Sentences II and Number Sentences and Story Problems are similar Level 3 resources.
