How to Use Drill Sheets Without the Tears
Start with a no-regrouping bridge set
Regrouping is where most math-page meltdowns begin, so treat it as its own unit. Before a child ever meets carrying, print a 20-problem set with the regrouping switch set to "no regrouping". Every problem there can be solved one digit column at a time, which lets the child practice the physical routine — start in the ones column, write the answer under the line — without the extra decision of what to do with ten. Two or three days of that, then switch to "only regrouping" so every single problem actually carries or borrows. Mixing the two too early is what produces the classic error of carrying on every problem, even 23 + 14. Our guide on teaching regrouping walks through the place-value language to use alongside these bridge sets.
Keep drills short and aim for 80% success
A drill sheet is a sprint, not a marathon. Ten to twenty problems in three to five minutes beats sixty problems in half an hour, because accuracy collapses long before effort does. Aim for a first-pass success rate around 80%: if a child misses more than one in five, the range is too wide — drop from 3-digit to 2-digit operands for a week and rebuild confidence. Mark the sheet together, circle the misses, and re-print the same operation the next day; the "New sheet" button gives you fresh numbers while keeping the exact difficulty identical. Score the page (the score line is built in) and let the child beat yesterday's score, not another child's.
Use big-font mode for tired brains
The ADHD big-font mode is not a novelty — it removes real friction. Larger digits with wider spacing mean fewer line-tracking errors (subtracting the wrong neighbor), more room for messy handwriting, and a page that looks finishable instead of a wall of numbers. Pair it with a timer the child can see, let them stand or sit on a wobble cushion, and check the first five answers immediately so feedback arrives while the problem is still fresh. One page done well every day beats three pages done in tears, and the answer key page lets a parent or self-checking student verify without a debate.
先用「不进位」过渡题组
绝大多数数学练习崩溃都发生在进位退位这一步，所以要把过渡当成独立阶段来做。在孩子第一次接触进位之前，把进位选项设为「只出不进位」，打印一份 20 题的练习：每道题都能逐位直接算，孩子可以专心练熟动作流程——从个位开始、答案写在线下——完全不用分心去想「满十怎么办」。这样练两三天后，再切到「只保留进位题」，让每道题都真实发生进位或退位。太早把两类题混在一起，就会出现「见题就进位」的经典错误，连 23+14 都要进位。配合《进位退位教学指南》里的位值语言使用，效果最好。
短时高频，守住八成正确率
口算练习是冲刺，不是马拉松。三到五分钟做十到二十题，好过半小时磨六十题——因为正确率的崩塌远远早于意志力的崩塌。第一遍正确率争取保持在八成左右：如果错得超过五分之一，说明数字范围太大了，退一档（比如从三位数降到两位数）练一周，把信心攒回来。批改时圈出错题，第二天用「重出新卷」按钮换一批数字，但难度完全保持一致；用页面上自带的得分栏，让孩子跟昨天的自己比，而不是跟别的孩子比。
累了就用大字号模式
ADHD 大字号模式不是为了新奇，它实打实减少了阻力：更大的数字和更宽的行距，意味着更少的「看错行」错误、更充足的空间容纳还不成熟的书写，以及一张看起来「能做完」的卷子，而不是一堵数字墙。搭配一个看得见的计时器，允许孩子站着写或坐在摇摆垫上，做完前五题立刻对答案，让反馈趁热到达。每天高质量地完成一页，胜过哭着完成三页——答案页还能让孩子自己核对，家长不用逐题判对错。
