Using Doubles to Subtract Printable Pack

Recall doubles addition facts from 1+1 through 10+10 fluently.

Use a known doubles addition fact to solve a related subtraction fact (e.g., knowing 8+8=16 to solve 16-8).

Apply the doubles-to-subtract strategy independently across twenty subtraction problems.

Confirm students have their doubles addition facts memorized before introducing this pack, since the strategy explicitly depends on that prior fluency, as the teacher note states.

Walk through the candy-bowl visual example as a group before assigning the six 'you try' items, since it models the exact reasoning students are expected to apply.

Use the thirty-item doubles-addition drill as a quick fluency check before moving to the subtraction practice page, to confirm the underlying facts are solid first.

Doubles addition fact fluency — students recall sums from 1+1 through 10+10 across a thirty-item drill.

Doubles-based subtraction strategy — students use a known doubles fact to solve a related subtraction problem, such as 8+8=16 leading to 16-8=8.

Independent strategy application — twenty final practice problems require students to apply the strategy without a worked example alongside each item.
