Personal pronouns and the mess of third grade
Most teachers hit a wall when they get to personal pronouns with third graders. The kids know the words, but they keep swapping them around in writing. I spent three years fighting the same battle before I realized the problem wasn't the pronouns themselves. It was the order I introduced them in. I used to start with the full chart: eu, tu, ele, ela, nós, vós, eles, elas. Then eu, mim, comigo, me, etc. That never worked. Kids mixed the subjective and objective forms within a week. The reason is simple: eighth-century grammatical tradition assumes children think like adult speakers. They don't.
The method that actually works
Start with the subject pronouns only. Eu, ele, ela, nós, eles, elas. That is six words. Not eight. Drop tu and vós entirely at this stage. Most Brazilian schools don't use them in speech anyway outside of specific regions, and introducing them creates confusion that lasts into fifth grade. After two weeks of the subject pronouns alone, add the object forms, but only the most common ones. Me, mim, comigo for first person singular. Te, ti, contigo for second person. Keep the rest for later. You are not teaching grammar comprehensively. You are teaching function. Third graders need to understand that "ele" does the action and "mim" receives it.
Here is a specific problem I encountered last year. A student kept writing "o João deu o livro para mim" and then immediately after writing "ele ler o livro." She understood the concept of case but not the convention of avoiding noun repetition once a pronoun is established. I stopped correcting the grammar and started correcting the style. We practiced one exercise: take a sentence with a repeated noun, replace the second mention with the correct pronoun. Just that. It took four sessions. Her writing improved dramatically after that because she finally saw the point of the exercise instead of treating it as arbitrary rules.

The real distinction third graders need to grasp is between the tonic and atonic forms. Tonic pronouns stand alone. Atônicos need a verb nearby. Most textbooks present them together from day one. That is a mistake. Present them separately, and only combine them once each set is solid. Here is a practical breakdown used in my classroom:
Subject pronouns: eu, tu, ele/ela, nós, vós, eles/elas. I drop tu and vós initially, as mentioned. The objective forms come next in two waves. Wave one: me, te, o/a, nos, vos. Wave two: mim, ti, si, conosco, consigo. The difference between "me" and "mim" trips up almost every kid. The workaround is simple and brutal: tell them mim never goes with a conjugated verb. If there is a verb next to it, it has to be me. That rule alone eliminates eighty percent of the errors in one lesson. Reflexive pronouns are another trap. Si is reflexive. Se is ambiguous. Kids conflate them constantly. I use a drawing exercise where a boy draws himself and writes "ele se olha no espelho" while another draws a different boy and writes "ele olha para si." Visual contrast works better than explanation at this age.

What does not work
Drill worksheets with ten pronoun substitution exercises per page. Children zone out after line three. The cognitive load is too high for sustained repetition at this developmental stage. Twenty minutes of targeted practice beats an hour of busywork every time. Teaching by translation from English or other languages. Brazilian Portuguese has structural differences in pronoun usage that do not map neatly. The result is fractured understanding. Stick to the language as it is actually spoken and written in Brazil.
Assuming regional variation is irrelevant. In Southern Brazil, "você" functions differently than in the Northeast. Some communities use "vocês" where others use "vós." A student from São Paulo might interpret "vós" as archaic nonsense. A student from Minas Gerais might use it in speech naturally. Acknowledge this. Do not pretend there is one uniform standard that applies to every child in the room.
A counter-intuitive point
Most curriculum guides recommend teaching pronouns alongside nouns and verbs simultaneously. That slows everything down. I found it faster to teach personal pronouns as a standalone unit for two weeks before connecting them to sentence structure. The isolated approach builds a stronger foundation. By the time we connect pronouns to syntax, the kids already recognize the forms. They just need to see how they fit into a complete sentence. That connection clicks much faster when the forms are already familiar. Another overlooked detail: the interaction between pronouns and indirect objects. "Dar para mim" versus "dar-me." Both are grammatically correct, but Brazilian usage heavily favors the prepositional construction in speech. Third graders absorb what they hear. If you teach only the clitic form, they will find it confusing when they encounter the prepositional version in real texts. Introduce both early, even if you emphasize one over the other.
Resources
There are decent worksheets available from the MEC portal and from state education secretariats. These are generally better than commercial publishers because they align with the BNCC competencies. The link for the basic set is available through the official government education platform. I also created a simple flashcard deck for my class using Anki, focused only on the subject and first-objective forms. It took about forty-five minutes to set up and saved hours of board writing over the semester. If you want something more visual, the Portuguese-language site da Sala de Aula helps with interactive exercises, though the interface is dated. Still functional. Search for "pronomes pessoais exercícios 3o ano" and you will find multiple free downloads.
Bottom line
Keep it narrow. Teach six subject pronouns first. Add object forms slowly. Use the mim rule. Draw pictures for reflexives. Avoid worksheets that rely on repetition. Acknowledge regional variation. Do not rush to combine everything at once. Third graders are not small adults. They need material scaled to their actual capacity, not to the expectations of a curriculum written fifty years ago.
