Focuses on identifying and representing numbers 20-100 using visual base-ten models.

Focuses on bar graphs and comparing data. Students analyze categories and count collections of mixed coins.

Focuses on picture graphs and dimes. Students interpret data with 1:1 correspondence and count mixed coins.

Focuses on tally charts and pennies/nickels. Students learn to read tallies and identify coins to 'buy' items from the market.

Students will solve word problems involving three addends, focusing on grouping numbers to find 'friendly' sums.

Students will explore the meaning of the equal sign by balancing equations where both sides contain operations.

Students will learn to solve for missing addends and subtrahends within 20 using counting-on and related facts strategies.

A preschool-focused lesson based on 'Benny's Pennies' by Pat Brisson, targeting one-to-one correspondence and rhyming through hands-on play.

Challenges students to choose the correct operation (addition or subtraction) based on word problem context. Includes problems within 20 and uses ten-frames for modeling.

Focuses on subtraction word problems (separating) by marking 'X's on pre-drawn images. Students transition from visual crossing-out to writing subtraction number sentences.

Focuses on addition word problems (joining) using farm-themed stories. Students practice drawing pictures and using ten-frames to represent addition equations.

Cette leçon porte sur la compréhension et la manipulation des nombres de 0 à 20 en utilisant les principes de la Conception Universelle de l'Apprentissage (CUA). Elle propose des parcours différenciés pour permettre à chaque élève de progresser à son rythme.

Focuses on hundred chart patterns, specifically identifying +1/-1 and +10/-10 relationships in grid sequences.

Focuses on skip counting by 2s, 5s, and 10s up to 100 using number series and patterns.

Focuses on visual subtraction models and simple +1/-1 missing number sequences within 20.

Day 3 covers probability and predictions, teaching students to identify 'more likely' and 'least likely' outcomes based on visual data.

Day 2 introduces pennies, nickels, and dimes, focusing on identifying values, using the cents symbol, and counting mixed coin groups.

Day 1 focuses on tally charts and bar graphs, emphasizing calculating sums and differences to compare data points.

A numeracy lesson helping students distinguish the number 12 from 20 and 21 using place value visualization (one ten, two ones) and 'Architect' inspection strategies.
