About lesson progress
Lesson marks record what you have studied. Checks show understanding separately. Guest marks come from this device.
- Count, compare and represent collectionsCount and compare sets of objects, then show one whole as two parts.
- Tens, ones and number wordsBundle ten ones to read, write and compare numbers up to 100.
- Combine and separate groupsUse parts and wholes to join, separate and compare collections.
- Related number storiesUse the same quantities to explain the inverse relationship between addition and subtraction.
- Patterns and positionsFollow a number rule and describe a position from a stated starting point.
- Choose a mental methodUse parts within 20; change ones without renaming, or add and subtract tens.
- Add and subtract with tensKeep the amount the same when you exchange one ten for ten ones, then add or subtract within 100.
- Equal groups and sharingBuild equal groups, count a product and divide by sharing or grouping.
