Ask Grade 4 Question or Post Answer/Comment

Send us your Grade 4 kids math question and we will attempt to provide a solution using the Model Method where possible.

Please post only 1 question per submission so that we can group the questions under different Concept Models to facilitate all users' future searches for similar questions.

There is no limit to the number of questions you can ask here, just post each question separately.

Visitors to this Forum can also post their answers to your questions.

If it is impossible or not efficient to solve using the Model Method, we will attempt to solve it using other Singapore Math Heuristics.
