💡 How to solve: Shape Sides & Vertices
Sides are the straight lines of a shape, and vertices are the corners where two sides meet. Count them one at a time and write the number.

💡 How to solve: 3D Shapes
A 3D shape is solid, not flat. A cube has 6 flat faces that are all squares. A cylinder is like a can with 2 flat circle faces, and a cone has 1 flat circle face and a point. A sphere is round like a ball and has no flat faces.

💡 2 + 4 = 6. So 3 + ___ must also make 6: 6 − 3 = 3.
✓ Correct!
Not quite. The answer is
💡 2 + 4 = 6. So 3 + ___ must also make 6: 6 − 3 = 3.
💡 How to solve: Column Addition within 20
Write the numbers one under the other with the ones lined up on the right. Add the ones first, then the tens. For 13 + 4: ones 3 + 4 = 7, tens 1 + 0 = 1, so 13 + 4 = 17. If the ones make 10 or more, like 8 + 5 = 13, write 3 in the ones place and 1 in the tens place.

Not quite. The answer is
💡 2 are taken away from 10. Break the ten: 10 is 10 + 0. Take 2 from the 10: 10 − 2 = 8. Then 8 + 0 = 8. So 10 − 2 = 8.
✓ Correct!
Not quite. The answer is
💡 2 are taken away from 10. Break the ten: 10 is 10 + 0. Take 2 from the 10: 10 − 2 = 8. Then 8 + 0 = 8. So 10 − 2 = 8.
💡 How to solve: Column Subtraction within 20
Write the bigger number on top with the ones lined up. Subtract the ones first, then the tens. For 17 − 5: ones 7 − 5 = 2, tens 1 − 0 = 1, so 17 − 5 = 12. If the top ones digit is too small, like 13 − 5, break the ten: 13 is 10 + 3, take 5 from the 10 to get 5, then 5 + 3 = 8.
