A targeted 10-minute intervention lesson using visual models to help third-grade students grasp the concept of equivalent fractions.

Advanced situations involving 'Start Unknown' and mixed problem types.

Solving word problems with three addends focusing on commutative and associative properties.

Solving word problems with three addends using the 'Make a Ten' strategy.

Exploring 'Compare' situations where the 'smaller' quantity is unknown.

Exploring 'Compare' situations where the 'bigger' quantity is unknown.

Introducing 'Compare' situations to find the difference unknown using connecting cubes.

Focus on 'Put Together/Take Apart' with one addend unknown using tape diagrams.

Introducing 'Take From' situations where the change is unknown using part-part-whole mats.

Introducing 'Add To' situations where the change is unknown using 'Mystery Box' models.

Focus on 'Put Together' and 'Take Apart' situations where the total is unknown.

Focus on 'Take From' situations with the result unknown using counters and visual crossing-out methods.

Focus on 'Add To' situations with the result unknown using concrete objects and five-frames.

Students learn the incrementing strategy to add numbers up to 100 by breaking the second addend into tens and ones and 'jumping' along a number line. This visual approach builds mental math fluency and place value understanding.

A lesson on addition within 100 using the incrementing algorithm. Students learn to break down the smaller part into its place values and add them step-by-step to the larger part using a "mountain jumping" visual theme.

A cumulative review and assessment day. Students complete a 'Final Inspection' quiz to demonstrate mastery and participate in a collaborative 'Lab Graduation' challenge.

Students apply their subtraction skills to solve complex, multi-step word problems. The lesson focuses on identifying keywords and creating 'evidence logs' to organize mathematical steps.

Addresses the specific challenge of regrouping when the minuend contains one or more zeros. Students learn the 'Middle Man' strategy to pass value from the hundreds place through the tens to the ones.
