Original PromptMath intervention plan for students struggling with mental addition stratagies
This resource introduces students to two effective addition strategies: the 'Make a Ten' and 'Doubles Plus One' strategies. The 'Make a Ten' strategy helps students solve addition problems by transforming them into simpler ones that involve the number ten, which is easier to calculate. Students learn to look for ways to adjust numbers in an equation to reach ten before adding any remaining values. The 'Doubles Plus One' strategy enables students to work with pairs of numbers that are one apart, doubling the smaller number and adding one to find the sum. The resource includes step-by-step instructions, practice problems, and visual aids like number lines to enhance understanding. Students are encouraged to apply these strategies through multiple exercises, allowing them to build confidence and improve their addition skills with the goal of achieving at least 80% accuracy.
