Praxis 5025 Practice Question
Problem, Decomposing addends into tens and ones, Composing addends into tens and ones, Taking away tens, then taking away ones, Taking away an extra ten, then adding back ones, Radio
Place the description of the strategy used to simplify the problem below the problem.
Correct Answer: A: Decomposing addends into tens and ones, B: Composing addends into tens and ones, C: Taking away tens, then taking away ones, D: Taking away an extra ten, then adding back ones
Rationale: Option A accurately demonstrates the strategy of decomposing addends into tens and ones, making it easier to perform the addition. By breaking 73 into 70 and 3, and 55 into 50 and 5, the addition becomes more manageable.
Option B incorrectly describes the strategy as composing addends, which is not applicable here since it involves addition rather than breaking down numbers.
Option C misapplies the strategy by suggesting taking away tens and then ones, which does not align with the operations performed.
Option D also misrepresents the approach, as it suggests taking away an extra ten, which complicates the process instead of simplifying it.
