The most basic and important thing in first grade mathematics is verbal ability. This 100-question oral calculation exercise covers addition and subtraction within 20, practicing one page per day, and the child’s calculation speed and accuracy can be significantly improved. A complete answer is attached at the end of the article to facilitate parental approval.
Verbal calculation is the foundation of primary school mathematics. If children in the first grade can’t pass verbal calculation, they will struggle to learn vertical calculations and apply questions later. Many parents report that their children will not, are slow, easy to make mistakes, and the root cause is to practice less.
This exercise is designed specifically for the first grade of elementary school:The first 50 questions are mainly based on additions and subtractions within 10to help children consolidate their foundations;The last 50 questions gradually transition to carry addition and subtraction within 20, the difficulty level is gradual. Each question has an answer line that can be printed directly.
Why is it important to practice math every day?
In the first-grade mathematics exam, oral calculation generally accounts for 30-40 points, which is the key to closing the gap. 10-15 minutes a day, do a page (about 20 questions) of oral calculation, adhere to a month, the child can complete 30 questions in 5 minutes, the accuracy rate is more than 95%, which has reached an excellent level.
Practice Suggestions
- Timing before questions: average 5-8 seconds per question, timeout to be marked;
- Copy the wrong question into the wrong question book, and redo the wrong question the next day;
- Do not use your fingers to calculate, encourage mental arithmetic and ten methods;
- After making progress, you can upgrade to less than 100 addition and subtraction.
Parent Coaching Tips
Don’t be in a hurry to criticize if your child makes a miscalculation. Ask him how he counts. Many times, it is a methodological problem. For example, 7 +8 is still wrestling his fingers. Teach him to “make ten dharmas”: 7 +8, make 7 into 10, it takes 3, 8 into 3 and 5, 10 +5 = 15. By the way, the speed naturally increased.
