Learning Objectives
- Count in 10s and 100s up to 1000.
- Use place value up to thousands.
- Read and write numbers in numerals and words up to 1000.
- Describe nearness using number lines.
- Compare numbers using =, >, < up to 1000.
- Generate patterns: even/odd and multiples of 2,3,4,5,10 up to 100.
Work through explanation slides, try examples, then practice with interactive activities.
Counting in 10s and 100s
Counting in tens: start at 0 or any multiple of 10 and add 10 each time. Counting in hundreds: add 100 each time.
Try start = 30, step = 10 to count 30, 40, 50 ... or start = 200, step = 100 to count 200, 300, 400 ...
Place Value (Units, Tens, Hundreds, Thousands)
Every digit has a place value. For example, 4 3 7 means 4 hundreds, 3 tens, 7 units → 437. For thousands, 1 2 3 4 = 1 thousand, 2 hundreds, 3 tens, 4 units → 1234.
Change digits and press Build Number to see the numeral and its place-value description.
Read and Write Numbers (Numerals & Words)
Type a number and convert it to words, or type words and convert to numerals. Use standard English words (and optional "and").
Number Lines — Nearness and Position
Use a number line to show how close a number is to another. Move the marker to see distance.
Example: From 0 to 100, point 37 is nearer to 40 than 30; describe using the number line.
Compare Numbers (=, >, <)
Choose a symbol and check whether the comparison is true. The tool will explain why.
Patterns — Even, Odd, and Multiples
Generate sequences to spot patterns and practice identifying even/odd and multiples.
